Ever wonder why old rockers keep on going on tour? Every year you hear about an old rocker that is hitting the road for a concert tour, and sometimes you think why?

I just figured it out, it's all about the money! Forbes just released this years list of highest paid musicians and one of the top earners was former Pink Floyd lead man Roger Waters raking in 88-million dollars!

He was not the only old rocker to make the list Elton John earned $80 million, U2 earned $78 million. Paul McCartney raked $57 million this year he ended up at number seven on the list. So it's no surprise that these guy's are still hitting the road, they can make so much cash why wouldn't they?
