A friend of mine was a guitar tech on quite a few Prince tours in the past. The man is an incredibly talented musician but weird personality would be putting it lightly. You didn't talk to Prince, nor look him in the eye, if he wanted to address you he would speak to his attache’ who would tell you (what you just heard), you responded to the attache’ who would repeat it back to Prince. Break on of the rules and you were off the tour, never to work for him again.
if you are a blues fan, look for a Japanese import video of Prince performing a night of the blues, absolutely incendiary.
