Mick Jagger’s song for Slow Horses is “Strange Game,” a theme he co-wrote and performed with composer Daniel Pemberton. The song began not with a conventional pop-song brief, but with an instrumental track Pemberton sent to Jagger. Drawing on the Mick Herron novels he had already read, Jagger quickly developed the lyrics, vocal ideas and chorus around Jackson Lamb and the disgraced MI5 agents exiled to Slough House.
Released on April 1, 2022, alongside the premiere of the Apple TV+ series, “Strange Game” became the opening-title theme and part of the show’s wider musical identity. Contemporary coverage described it as Jagger’s first television theme song.
The song behind Slow Horses
The track is titled “Strange Game”—singular, not “Strange Games,” which is also the title of a Season 3 episode. It was written by Mick Jagger and Daniel Pemberton, performed by Jagger and produced by Pemberton. The digital single runs approximately 3 minutes and 32 seconds.

Why the production wanted Mick Jagger
Director James Hawes wanted the series to have a musical voice with the same combination of gravitas and swagger as Jackson Lamb, the foul-mouthed, apparently unbothered spymaster played by Gary Oldman. Music supervisor Catherine Grieves was also involved in shaping that brief.
Jagger was reportedly Hawes’s preferred choice from the beginning, although the production team initially assumed that persuading a Rolling Stone to write a television theme was unlikely. Composer Daniel Pemberton eventually contacted Jagger by email to ask whether he would consider writing one.
Jagger’s familiarity with the material made the proposal more plausible. Pemberton later said that Jagger already knew Herron’s books and was also aware of some of Pemberton’s previous work, including “Hear My Voice” from The Trial of the Chicago 7. The account of how the collaboration came together is detailed in Variety’s interview and in a contemporary AppleInsider report.
Jagger already understood the world of Slough House
Jagger had read approximately three or four of Mick Herron’s Slough House novels before working on the song. That gave him an immediate sense of the series’ characters, its grim London atmosphere and Lamb’s particular personality.

Most importantly, he understood the contradiction at the heart of the story: the Slough House agents are treated as failures and outsiders, but many still want to prove that they belong at the center of British intelligence. They may be damaged, compromised or incompetent, but they have not entirely abandoned the ambition that brought them to MI5.
Jagger completed the song before watching the filmed episodes. His starting point was the books, Pemberton’s instrumental, the project’s briefing material and a trailer or package supplied to his team—not a viewing of the finished television series. That helps explain why the song feels connected to the characters without functioning as a scene-by-scene musical summary.

From an instrumental track to a finished song
Pemberton did not send Jagger a finished song with an established lyric and vocal melody. He sent an instrumental foundation: an unusual, deliberately rough-edged piece of music built around lo-fi recording techniques and what Pemberton described as “wonky” sounds.
The collaboration developed remotely during the COVID period:

- Pemberton supplied the musical starting point. He played the track to Jagger over Zoom, including a guitar presentation of the material.
- Jagger made an immediate lyrical response. He said he quickly “dashed off” notes about what he thought the music and the story were about.
- He recorded early ideas on an iPhone. Those rough demos included vocal approaches, lyric fragments and possible melodic directions, which he sent back to Pemberton.
- The pair searched for the chorus and title. Jagger initially thought the obvious title might be “Slow Horses,” but Pemberton did not want simply to use the series title.
- Pemberton reshaped the arrangement. As Jagger’s vocal and chorus ideas developed, Pemberton revised the musical track around them rather than treating the instrumental as a completed composition.
- They completed the recording remotely. Their communication continued through Zoom, email and text messages before later studio work took place.
Pemberton later recalled that the work unfolded over a couple of winter months. When Jagger’s studio in Mustique was unavailable, Jagger used a backup studio on a neighboring island to send additional vocals. That detail comes from Pemberton’s later recollection and does not mean that every part of the recording was made in Mustique.
Who wrote what?
It is too simple to say that Jagger wrote the entire theme alone. The formal credits list both Jagger and Pemberton as songwriters, while the interviews describe a clear but collaborative division of labor.
| Contributor | Contribution |
|---|---|
| Mick Jagger | Lyrics, vocal ideas, vocal performance and a songwriting contribution shaped around the characters’ point of view. |
| Daniel Pemberton | Original instrumental foundation, additional songwriting, production, arrangement and integration with the series score. |
Apple Music’s track credits list Jagger as the vocalist and identify Pemberton on guitar, piano, bass and electronic percussion. Pemberton’s role therefore went beyond supplying a backing track: he created the sonic framework, co-wrote the song and connected it to the musical language of the series.
Why is the song called “Strange Game”?
The title describes the morally ambiguous, unstable world inhabited by the Slough House agents. Jagger’s first instinct was reportedly to call the song “Slow Horses,” but Pemberton rejected the direct reuse of the show’s name. Jagger then proposed “Strange Game.”

That phrase also captures the characters’ peculiar position inside MI5. They are still part of the institution, but they have been removed from the prestigious center of it. Their work is humiliating and often absurd, yet the stakes remain serious. They are playing an espionage game in which the rules are unclear, loyalties shift and professional survival can depend on recovering lost status.
The chorus centers on the desire to get back into the world of the “big boys”—the headquarters, authority and relevance from which the agents have been excluded. It is both a joke at their expense and an expression of their ambition.
Jackson Lamb’s voice, and the agents’ humiliation
Jagger explained that he wrote parts of the verses from Jackson Lamb’s perspective. That does not make the song a literal monologue from Lamb, but it gives the lyrics his contemptuous, irreverent attitude toward the people under his command.
The verses mock the agents as damaged outsiders and professional disappointments. At the same time, the song recognizes that they want redemption. The tension between ridicule and sympathy is central to the track: Slough House is a place for people who have failed, but failure does not necessarily make them useless.
That perspective gives “Strange Game” several overlapping themes:
- Failure: the agents have been sidelined because of mistakes or perceived shortcomings.
- Exile: they remain within MI5 but have been banished from its most important rooms.
- Survival: they continue operating in an institution that would prefer to forget them.
- Redemption: they still hope to return to the center of power and prove themselves.
- Ambiguity: the line between heroism, incompetence and manipulation is never stable.
Jagger described Lamb as irreverent and characterized the song as a mixture of that irreverence with something eerie. The result is not a straightforward heroic spy anthem. It sounds more like a taunt from someone who knows exactly how ridiculous the agents look—and how dangerous they may still be.

What does “Strange Game” sound like?
Jagger compared the track’s atmosphere to Kurt Weill while emphasizing that it retained a blues influence without becoming a conventional blues song. Contemporary descriptions of the recording point to a shuffling guitar-and-percussion foundation, intermittent piano, lo-fi textures and a vocal that shifts between whispering, sneering and swaggering.
That combination is important to the show’s tone. The music has the strut associated with Jagger, but it is deliberately crooked and uneasy rather than polished. The rough textures suggest a world of shabby offices, compromised institutions and people who are never quite as competent—or as incompetent—as they appear.
Pemberton’s instrumentation helps keep the track from sounding like an unrelated Jagger solo recording placed over a television sequence. Guitar, piano, bass and electronic percussion establish the rhythm, while the production leaves room for odd noises and unstable edges. Jagger’s voice supplies the recognizable swagger, but the arrangement repeatedly undercuts it with menace and discomfort.
Jagger’s harmonica also appears occasionally in Pemberton’s underscore beyond the main recording. That is a small but revealing detail: the collaboration influenced parts of the series’ musical texture rather than ending with the delivery of the theme.

The opening-title sequence was created by UK studio Momoco. It introduces the cast and the Slough House world through animation while the song establishes the series’ grimy, comic and outsider tone. Production credits identify Apple TV and See-Saw Films as the client and Momoco as the studio; the credits are documented by GEMA.
Pemberton also built the score so that elements of “Strange Game”—including its riff and smaller sonic fragments—could recur elsewhere. The theme therefore operates as a musical idea within Slow Horses, not merely as an opening signature that disappears once the titles end. The related cue “Slough House (Strange Game)” on the first-season soundtrack makes that connection explicit.

Release details and where to hear it
“Strange Game” was released on April 1, 2022, the same day that Slow Horses premiered on Apple TV+. The single was issued through Polydor/Universal under a license involving Apple Video Programming. It is available through the Apple Music single page, and Jagger’s official lyric video was published on his official YouTube channel on the same date.
The first-season soundtrack includes the main song as well as “Slough House (Strange Game)” and other score material. Listening to both versions makes the relationship between Jagger’s theme and Pemberton’s underscore easier to hear.
Important credit and award distinctions
Several descriptions of the song can create avoidable confusion:
- Jagger did not write the entire song alone. Both Jagger and Pemberton receive songwriting credit.
- Jagger did not compose the entire Slow Horses score. Pemberton created the series’ score and incorporated material associated with the theme.
- It is not a song called “Slow Horses.” The series is called Slow Horses; the theme is “Strange Game.”
- It is not only an end-credit song. Its principal television use is over the opening titles, with related material appearing elsewhere in the score.
- A nomination is not a win. The official 2022 Hollywood Music in Media Awards list records “Strange Game” as nominated in television-song and main-title categories; it should not be described as a confirmed winner on the basis of that listing.
- The 2024 Emmy recognition is a separate matter. The Television Academy nomination concerned Pemberton and Toydrum’s original dramatic score for the episode “Strange Games,” not a standalone songwriting award for “Strange Game.”
Current Slow Horses status
The story of how “Strange Game” was made belongs to the show’s 2022 launch and should not be mistaken for a new release announcement. As of August 10, 2026, Apple lists the first five seasons as streaming and says Season 6 is scheduled to premiere on September 16, 2026. The original coverage and release materials called the service Apple TV+; Apple’s current 2026 press materials use the shorter name Apple TV. See Apple’s Season 6 announcement and its current series page for the latest platform information.

“Strange Game” works because it is neither a generic spy theme nor a solo Jagger track pasted onto a television show. Pemberton created its strange, lo-fi musical world; Jagger used his knowledge of Herron’s characters to give it a sneering voice, a memorable chorus and a point of view rooted in failure, exile and the desire to get back among the “big boys.”
