If You Could Hang With One Rock star Dead or Living Who Would it be?

I'm sure we've all thought about this at one time or another.  If you could hang out with one rock star.  Dead or living who would it be?

I would love to have a couple drinks with Janis Joplin.  Just one of a many that we lost at the young age of 27.  Would ask about the Monterey Jazz Fest, Big Brother, and have a ton of questions about cheap thrills.  OK, your turn.  Who would you like to speak too?
