Witness 4 The Prosecution is an unreleased track initially recorded on 27 March 1986 at Prince's Galpin Blvd Home Studio in Chanhassen, Minnesota (two days after Love And Sex, on the same day as Movie Star and A Place In Heaven). Further recording was done by Wendy Melvoin, Lisa Coleman, Susannah Melvoin and Eric Leeds on 15 April 1986 at Prince's Galpin Blvd Home Studio while Prince was en route returning from France shooting additional scenes for Under The Cherry Moon (on the same day Lisa Coleman recorded Visions).
While the track was not included on a late April 1986 configuration of the Dream Factory album, it was included as the 17th track (15th song) on the 3 June 1986 configuration, and as the 16th track on the 18 July 1986 configuration.
Prince re-recorded the track completely on 6 October 1986 (the day after Rescue Me and the day before disbanding the Revolution and recording Telepathy) at Sunset Sound in Hollywood, California. It is not known if this re-recording was intended for any specific project.
In late 1998 / 1999, the track was intended for inclusion on the Roadhouse Garden album of Prince and the Revolution-era tracks (indicating that it would have been the 15 April 1986 version of the song), but this album remains unreleased.
