This Is My Song is a famous ballad recorded by the British singer Petula Clark and released in 1967. Uniquely and surprisingly, the music and lyrics were written entirely by the silent film legend, Charlie Chaplin, for his final film, A Countess from Hong Kong. Petula Clark initially assumed her recording would only be an album track, but it turned into one of the biggest hits of her career, topping charts across the globe. (Written by): Charlie Chaplin. (Year Written): 1966. (Release Year): Ear
