Uh Huh is an unreleased song recorded on 7 March 1991 at Larrabee Sound Studios in North Hollywood, California (it was copyrighted on 15 October 1991). The track is an upbeat blues/funk track, with lyrics promoting a positive, spiritual, mindset. It contains samples of Ray Charles playing piano from a popular Diet Pepsi commercial from the time, and uses the drink’s slogan (also used in the commercial), "You got the right one, baby! Uh huh", as part of the chorus.
It is not known if the track was intended for his next album, Diamonds And Pearls, or any other project. It is possible that, if released, the track would have been credited to Prince and the New Power Generation, but as other members of the band are not believed to have participated in the recording, it is included here as a ’solo' Prince track.
Prince’s recording of this track has often led to the mistaken belief that Prince wrote the jingle used in the commercials; in fact it was written by Diet Pepsi creative director Alfred Merrin and jingle writer Peter Cofield, who tried to tailor the catchphrase "the right one" to Ray Charles' delivery and consequently added "baby." Charles' backing singers The Raelettes then added "Uh huh" after playing around with other two-syllable alternatives, such as "doo-woo".
