"Slave" was eventually recorded for "Tattoo You" but there is the original 10 minute long version know as "Black And Blue Jam" or "Vagina", recorded in 1975 ( between 22nd January - 9th February: Rotterdam, Holland, De Doelen, Mobile Record Unit) and 1980 ( 11th October - 12th November: Boulogne-Billancourt (near Paris), France, Pathé-Marconi Studios).This long version was compiled of two cut up tapes from different sources creating the ultimate and finally complete version of "Slave". For more information, see the clip in the credits.Cheers!
