Music composed by Charles Chaplin
Terry auditions for Mr. Postant as Neville plays the piano, Limelight (1952). Melissa Hayden, a dancer with the New York City ballet, doubles for Claire Bloom in this scene (as well as all of the dance scenes in the film).
After Terry's audition, Calvero, who had been watching the audition in the wings, is left alone in the theater and the lights are shut off around him.
Note: One of the tunes Neville plays in this scene is the same tune the kid making cookies at the progressive school in A King in New York is humming.
