John Foster’s tearful American Idol performance of “Tell That Angel I Love Her” was a personal tribute to his late friend Maggie Dunn. Here is what happened, why the song mattered, and where viewers can look for the official clip.
John Foster’s tearful American Idol performance was a deeply personal tribute, not simply another attempt to win over the judges. During the April 20, 2025 “Songs of Faith” episode, the Louisiana singer performed his original song, “Tell That Angel I Love Her,” for his late friend Maggie Dunn.
Foster had already reached the show’s Top 20 when he delivered the song. Near the end of the performance, the emotion became visible and he struggled through the final moments before saying, “I love you, Maggie.” The result was one of the most revealing performances of his Season 23 run.
Why John Foster became emotional
Foster wrote “Tell That Angel I Love Her” in memory of Maggie Dunn, his best friend. Louisiana House Resolution 166 records that Dunn died on New Year’s Eve in 2022 and identifies Foster as the writer of the original song honoring her.

Reports about the tragedy also refer to Caroline Gill, but the official state resolution specifically identifies Maggie Dunn as the person honored by Foster’s song. The performance is therefore best understood as Foster’s personal memorial to Dunn, while the broader circumstances should be described carefully rather than assumed from less-specific accounts.
The song’s subject gave the performance unusual weight, but its impact also came from Foster’s decision to sing an original composition. Instead of relying on a familiar country standard, he introduced viewers to his own writing and to the emotional perspective behind it. His reaction at the conclusion appeared spontaneous and made the moment feel less like a competition number than a private remembrance shared with the audience.
The judges praised a more tender side of his voice
The judges responded positively to the performance. Carrie Underwood praised the throwback quality of Foster’s voice and style and said the song revealed a tender side of his vocal identity. Luke Bryan said the performance answered doubts about whether Foster belonged in the competition.
The comments were significant because Foster had been developing a recognizable neo-traditional country style. The tribute showed that his appeal was not limited to a polished, old-fashioned country sound: he could also use that voice for a quiet and vulnerable personal story.
Who is John Foster?
Foster is from Addis, Louisiana. Louisiana House Resolution 166 describes him as an 18-year-old native of Addis, the 2024 valedictorian of Brusly High School, and an LSU pre-med student pursuing music. The resolution characterizes his musical approach as “neo-traditional.”
That combination of academic ambition, Louisiana roots, traditional country influences, and original songwriting shaped his identity on American Idol. The Maggie Dunn tribute was one part of a broader season in which Foster balanced original material with established country songs.
For example, he later performed Brooks & Dunn’s “Believe” as a Mother’s Day dedication to his mother, Amanda. That performance provides useful context for his ability to connect songs with family and personal relationships, but it is separate from “Tell That Angel I Love Her,” the original song dedicated to Maggie Dunn.

Its importance came from what it revealed about him: Foster was not only a young country vocalist competing for votes. He was also a developing singer-songwriter using the national stage to honor someone he had lost. That personal purpose, combined with the original song and his tearful final dedication, explains why the performance became a defining moment of his American Idol story.
