In the late 1920s, as Weimar Germany careened towards fascism, the British writer Christopher Isherwood moved to Berlin. Living with a flapper who had Hollywood ambitions, he spent his evenings at the city’s jazz cabarets and was a loyal customer of the local male prostitutes. These escapades inspired Isherwood’s 1939 novel, Goodbye to Berlin, which inspired John Van Druten’s 1951 play, I am a Camera, which inspired the John Kander–Fred Ebb–Joe Masteroff 1966 musical, Cabaret. The musical follows the love life of Sally Bowles, a Jazz-age singer at a seedy cabaret called the Kit Kat Klub, and its debut production on Broadway earned two Tony Awards. In 2021, the latest in a long string of revivals opened in the West End and starred Eddie Redmayne as the club’s emcee. The Olivier Award-winning production, along with Redmayne, now heads to Broadway. —Jensen Davis
