The original 1966 version of this portrait of German life in the early 1930s-with a book by Joe Masteroff and a classic score by John Kander and Fred Ebb-scrubbed the gayness from its source material, Christopher Isherwood's 1939 novella Goodbye to Berlin. Cabaret ’s unusual evolution gives it a special place on this list, as its relationship to gay content has been in a continual state of flux.
