When I think "rock star," I think of moments such as Paul Simonon smashing his bass on the cover of "London Calling," John Lennon's bed-in with Yoko Ono, or Bob Dylan's responding "play it [expletive] loud" to fans booing him for going electric. What unites these moments are the expressions of opposition to the status quo, as well as a belief that their actions could influence the world around them.
