Green Day has donated an autographed guitar to Charitybuzz to raise money for Dancin Power, an organization who teaches interactive dance lessons to hospitalized children.

The guitar, a Fender Squier model, was donated by the band last month and is signed by Billie Joel Joe, Mike, and Tré. Bidding on the guitar, which has a placed value of $8,000, ends on the afternoon of April 20th.
