About the film
40 Years in the Making: The Magic Music Movie is a 2017 American documentary film written and directed by comedy writer Lee Aronsohn about Magic Music, a folk music band that broke up in 1975 before ever releasing a record. They were big in Boulder, Colorado, where Aronsohn attended University of Colorado Boulder. After Aronsohn's retirement from The Big Bang Theory, Aronsohn decided to make the documentary about the band and try to get them to reunite to play one more show.
