Do I Do

The album version of the song is ten and a half minutes long and features a rare example of Wonder rapping near the end of the track. Dizzy Gillespie also appears on the track with a trumpet solo. Both of these elements are omitted from the single edit of the song (some longer edits retain the Gillespie solo but exclude the rapping). Wonder audibly counts down at the end of the track. The song is noted by bassists for its intricate bassline, played by Nathan Watts.^[6] A commercial success, it received three Grammy Award nominations including for Best Male R&B Vocal Performance and Best R&B Song. The song became the basis for Ja Rule's "Livin it Up."
