Gaye would compose five different versions of the title track, including an alternate vocal version, which was used primarily for the film's intro. The alternate version featured Gaye double-tracking two lead vocal parts into one, bringing his falsetto vocals with his tenor on top of the falsetto. The single version, which was also featured on the soundtrack, would feature a single lead vocal take. The other three versions were put on the album as instrumentals with Gaye providing synthesizer keyboards while saxophone solos (and occasionally guitar) accompany him.
