Eddie Vedder of Pearl Jam teamed up with Jimmy Fallon on Thursday’s episode of ‘Late Night With Jimmy Fallon’ to perform a song titled ‘Balls in Your Mouth.’ It all starts off with Fallon strumming an acoustic guitar and singing a protest song about last year’s BP oil spill in the Gulf of Mexico. The Roots then come in with a backing groove, and as the chorus hits, none other than Eddie Vedder joins in. Another classic video from Fallon! Watch it below:

Later in the show Eddie and Pearl Jam perform a new song titled ‘Ole!.’ You can visit PJ20.com to download the studio version of the track as well. The show also featured an interview with Cameron Crowe, who directed the forthcoming documentary, ‘PJ20.’
