On July 20, 1961, a new musical opened at the Queen’s Theatre in England. The musical was called Stop the World, I Want to Get Off, and was co-written, directed by, and starred Anthony Newley. The show was a smash, went to
Broadway and Newley became an instant superstar. From there it was more shows (Roar of the Greasepaint, Smell of the Crowd), films, as writer, director, and actor, sometimes all three at once (Can Hieronymus Merkin Ever Forget Mercy Humppe and Find True Happiness, Willy Wonka, Doctor Dolittle), TV (tons of guest shots on every variety show of the era), and concerts all over the world.
