"Smile" is a song based on an instrumental theme used in the soundtrack for the 1936 Charlie Chaplin movie Modern Times. Chaplin composed the D minor music, while John Turner and Geoffrey Parsons added the lyrics and title in 1954. In the lyrics, based on lines and themes from the film, the singer is telling the listener to cheer up and that there is always a bright tomorrow, just as long as they smile. "Smile" has become a popular standard since its original use in Chaplin's film.
