Bob Fosse's 1972 film adaptation of CABARET, just like the film adaptation of WICKED did with Gregory Maguire's original novel and Broadway production, used both the original source books by Christopher Isherwood and the 1966 Broadway production. Bob Fosse's concept was to keep CABARET in a realistic setting therefore chose to keep all the musical numbers (aside from the outdoor "Tomorrow Belongs to Me" number) performed strictly inside the Kit Kat Klub. All the book songs were cut from the written script including the characters that sang them, even though they are seen briefly and instrumental versions of cut songs underscore scenes. What you see in the film is exactly what was filmed. John Kander and Fred Ebb wanted new songs in the film which is why several "performance" songs from the original Broadway production were replaced with new songs ("Mein Herr", "Money, Money, Money", and their recycled "Maybe This Time"). The multi-Oscar winning film released theatrically in 1972 is exactly what was greenlit and filmed.
