Cabaret is a musical based on a book written by Christopher Isherwood, music by John Kander and lyrics by Fred Ebb. The 1966 Broadway production became a hit, inspiring numerous subsequent productions in London and New York, as well as the 1972 film by the same name. It is 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 is based in nightlife at the seedy Kit Kat Klub, and revolves around the 19-year-old English cabaret performer Sally Bowles and her relationship with the young American writer Cliff Bradshaw. 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 the threatening state of late Weimar Germany.
