This song was written for the 1955 musical film It’s Always Fair Weather, in which Ted Riley (Gene Kelly) escapes from gangsters by blending in with the crowd at a roller-skating rink. Once safe, he glories in the love of a good woman that has cured him of his self-loathing.
The song is less famous than the dance number that accompanies it in the film, in which Kelly tap dances on roller skates through a crowded street.
