Van the Man
Do you think Van Morrison would have been a member of Bruce Springsteen's tour a few months ago? Here's an interesting quote from an interview in 1973:
"I think a musician who gets involved in politics is way out of his depth. Unless it's somebody like Pete Seeger who really knows what he's talking about. I think most of them can't cut it. Guys like Pete Seeger have been through all that and that's why they can talk about it. I think it's terrible for musicians to use their position to influence people like that. They don't have any right."

No wonder he's the President's favorite musician.
