In addition to his filmmaking, Chaplin wrote the musical scores for most of his most popular films, such as The Kid, City Lights, and The Great Dictator, though he had no musical training. The theme music for his last movie, The Countess of Hong Kong, was released with vocals recorded by Chaplin’s neighbor, vocalist Petula Clark -- and the song, "This Is My Song," was one of the most popular singles of the year.
