It seems like 95% of my outtakes are from the '80s, while most of my live shows are from the '90s. Anyone else?

The reason that alot of outtakes are from the 80's is that Prince didn't have a lot of control over the studios that he recorded in and people who worked there. Since he started to clamp down on who worked for him and because he now records in his own studio, the bootlegers have been out of the loop. Some songs do get out, but not as much as they used too. This information was grabbed from Utown's Days Of Wild book if you need more.
