The song is sung as a duet with Apollonia Kotero, and was originally intended to be performed by Vanity but shortly before filming began on the movie Purple Rain, Vanity famously chose to quit participation in the film altogether when she was offered what appeared to be a lucrative contract with Motown Records exec Berry Gordy and began filming The Last Dragon (An early demo of the song exists with her vocals and has circulated on bootleg recordings by collectors.)

As a result of this addition, Prince made cuts to the suite-like original "Computer Blue", which circulates among collectors in an extended version (a portion of this second section of "Computer Blue" can be heard in the film Purple Rain as Prince walks in on the men of The Revolution rehearsing).

Cash Box said that the song has "some beautiful melodies and some well-placed string sections which are proof of Prince’s varied talents.

[5][6][7] In the UK, the song was issued as a double A-side single, coupled with "Let's Go Crazy", reaching number 7 in March 1985.
