//Grammy Events: More From MusiCares Signings Day 1 – Jonas Brothers//

51st annual Grammy Awards Best New Artist nominees the Jonas Brothers spent a little time giving back to charity before their big day Sunday. The guys signed some sweet guitars to be auctioned for MusiCares last night at the Staples Center in LA.
