The instrumental score for Oliver & Company was composed by J. A. C. Redford, and the film's music was supervised by Carole Childs. The first song heard in the film, "Once Upon a Time in New York City", was co-written by lyricist Howard Ashman, who, with Alan Menken, would write the songs for the next three Disney films. Billy Joel, in addition to voicing Dodger, performed the character's song in the film.
