Disc 3 - Outakes From the vault
1. The Dance Electric 11.29 - Prince version of a song given to Andre Cymone in 1985
2. Love and Sex 5.00 - Previously unreleased
3. Computer Blue (Hallway speech mix) 12.12 - This was the extended version of Computer Blue with Wendy and Lisa talking in middle
4. Velvet Kitty Kat 2.42 - Unreleased out take from 1981 as Mink Kitty Kat for Vanity6, this version is from 1983 and has Morris Day Vocals, apparently a groove with filthy lyrics.
5. Katrina's Paper Dolls 3.30 - Another Mysterious song I know little about. It is not on any of my bootlegs.
6. We Can F**k 10.17 - Unreleased 1st version of We can funk, this is quite long and funked out and has controversial lyrics and subject matter.
7. Electric Intercourse 4.57 - Legendary track played in the August 1983 concert, this is a studio version, a great sexualised ballad and one of his finest ever songs.
8. Our Destiny/Road House Garden 6.25 - More very highly regarded music in the vein of Around the world in a day - great stuff.
9. Possessed 7.56 - another great song with some very explicit lyrics and a funky beat.
10. Wonderful Ass 6.24 - Another unreleased gem with upbeat dancey feel and some lyrics that would make Michael Jackson blush.
11. Fathers Song 5.30 - The Piano track you hear in the movie, a nice piano feel with some lovely chords.
Overall, this is the disc most will be wanting. Most of these songs have circulated as bootlegs for years and at least 4 of them are in the top level of all Prince songs (Electric Intercourse, Possessed, Wonderful Ass, Our Destiny/Road House Garden) and the extended Computer blue is also a favourite. This version eliminates the last 3 minutes of guitar feedback.
Part of the reason, the songs on Disc 3 have never seen the light of day, is that all contain very graphic lyrics and sexually charged themes (with the exception of Fathers Song). At the time Prince was trying to cross over to a huge audience and wanted to tone down the extreme sex of the Dirty Mind/1999 era (1980 - 1983). Despite this, Purple Rain was a huge success, but became known for its raunchy sex scenes and songs like Darling Nikki were offensive enough to get Tipper Gore's knickers in a twist. Also it got the attention of Michael Jackson who liked the music but found the movie degraded women and Prince was a rather nasty and self obsessed person.
There is criticism that there was no release of the Protege songs including Jungle Love and The Bird by the Time, Sex Shooter by Apollonia 6 and the legendary Modernaire by the Modernaires a group set up by Prince's ex guitarist Dez Dickerson. All of these songs except Modernaire were written by Prince.
There is a rumour 2 concerts are also to be released, one being the March 1985 Syracuse concert originally released as "Prince and the Revolution Live" on VHS/Beta Cassette in 1985. The other show is reputed to be the August 3rd 1983 First Avenue concert in which most of the songs were played for the first time and Purple Rain/Baby I'm a Star/Lets Go Crazy and I would die 4 U were placed on the Purple Rain album. (All the performances in Purple Rain, the movie are lypsynched). This show also had A case of you and Electric Intercourse on it along with several 1999 songs like Automatic and Delirious.
