Eddie Vedder likes to get up on stage with people. This happened in Chicago earlier this week, jumping on stage with rock legend Roger Waters. I’ve witnessed him twice getting up on stage with artists, like U2, and Bruce Springsteen. He must have a pretty wicked address book in the ol’ iphone. I always wonder, who calls who? Does the artist call? Or does Eddie just say, hey man, can I come to the show tonight, I’ll sing for my ticket!
