After Paul McCartney played his first tune at last night's Concert for Sandy Relief (presented by Chase), he made a point of showing off the bass-guitar before a stage-hand took it away. That's because Paul's instrument from last night's incredible show is up for auction! In fact, many items from the 12/12/12 stars are up for grabs today, and the money will go to benefit the communities affected by Superstorm Sandy.

Even if the current bid on Paul's bass-guitar ($36,000 as of this writing) is too steep for you, it's still fun to look at what Alicia Keys, Roger Waters, and even President Bill Clinton are offering. Check out the auction items here.
