Don is a little off on his facts.  Prince wrote and produced this for his then girlfriend Vanity.

Maybe this will...  Umm....drive you wild.  No body does the tempo di fuck like Prince.   Nice guitar work if you can take your mind off V's perfect ass.

This is the radio version I believe. On Soul Train, understandably, they couldn't do the spoken word/rap part.
