The tender ballad is built around the piano and synthesizers and features live drumming and bass.

The emotional lyrics delivered by Day tell of a difficult breakup and that he is still in love with the song's subject.

The U.S. 7" single was backed with an edit of album track, "The Stick", a funky number which was written by Revolution member Lisa Coleman (uncredited), who also provided background vocals.

Another uncredited Revolution member was Doctor Fink, who provided synthesizer solos for the track.

Though not one of their biggest hits, "Girl" is often played in concert and a live version of the song recorded at the House of Blues in 1998 and was included on Morris Day's 2004 album, It's About Time.
