Cabaret is a 1966 musical with music by John Kander, lyrics by Fred Ebb, and book by Joe Masteroff, based on John Van Druten’s 1951 play I Am a Camera, which was adapted from the short novel Goodbye to Berlin (1939) by Christopher Isherwood. Set in 1931 Berlin as the Nazis are rising to power, it focuses on the nightlife at the seedy Kit Kat Klub, and revolves around young American writer Cliff Bradshaw and his relationship with English cabaret performer Sally Bowles.
A sub-plot involves the doomed romance between German boarding house owner Fräulein Schneider and her elderly suitor Herr Schultz, a Jewish fruit vendor. Overseeing the action is the Master of Ceremonies at the Kit Kat Klub. The club serves as a metaphor for ominous political developments in late Weimar Germany.
