Bono, Jovi and Bill Who's the Bigger Rockstar!?

It was an aging rock star convention last night as Bono, former President Bill Clinton and Jon Bon Jovi joined forces at a charity event in NYC.


Fun fact: While 48-year-old Bono has over 20 Grammy awards, 62-year-old Clinton actually beats Bon Jovi with two Grammy wins (Best Spoken Word category) to the 47-year-old's one.

These days you don't even need to know how to sing to make it in the record biz.
