The song is sung as a
duet with
Apollonia Kotero. It was originally intended to be performed by
Vanity. 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.) She ceased her romantic relationship with
Prince. The song was then intended for the
Apollonia 6 album to coincide with the film, but was pulled for the
Purple Rain soundtrack. 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). The original version of the song was about a minute longer. ==Reception==
