Question: is cabaret a concept musical?
Answer: Cabaret: A concept on top of a concept musical. ... "Life is a cabaret, old chum," sings Sally Bowles in the 1966 musical that plays out like an evening at a Berlin club during the dying days of the Weimar Republic. Because of their built-in concepts, Kander and Ebb's musicals are more easily refreshed than reinvented.
