 The film features a score composed by a young, pre-Mothers of Invention Frank Zappa.During a 1963 appearance on "The Steve Allen Show", on which he generated musical sounds on bicycles, Zappa talked about scoring the soundtrack for "The World's Greatest Sinner", which he called "the world's worst movie," even though the general public would not have the opportunity to see the film he was talking about for another 50 years.During the course of this same interview with Steve Allen, Zappa discusses how he recorded the soundtrack for this film in the Little Theatre, located at Chaffey College in Alta Loma, California, along with the plethora of instruments used.
