Wow is an unreleased track recorded in mid-April 1992, at Platinum Studios, Melbourne, Australia (while also on the Diamonds And Pearls Tour, during the same set of sessions as Don’t Talk 2 Strangers, Poor Little Bastard, The Rest Of My Life, There Is Lonely, Be My Mirror, 51 Hours and re-recordings of Make Believe and I’ll Do Anything). The song was written specifically for the James L. Brooks movie I’ll Do Anything, and the track was re-recorded by the ensemble cast for the movie, basically as a solo vocal performance by Tracey Ullman and was weaved into the movie at six different points during a rough cut of the movie (one of these scenes involved a childbirth sequence (cut from the final film) in which a woman sings "ow" instead of "wow"). One of these versions (it is not clear which one) was included as the first track on a planned I’ll Do Anything album. While Prince was not directly involved in this version, it is included in the listing here as his own version remains unreleased and was intended as a demo for the soundtrack version. When preview audience reactions to the music were overwhelmingly negative, all production numbers from the film were cut, and the album was abandoned. The song remains unreleased.
While the track shares a title with the Prince and 3rdEyeGirl track Wow, the tracks are otherwise unrelated.
