The newly reunited Ween performed at Bonnaroo over the weekend, and after their set, Dean Ween had a little backstage jam session with fellow Bonnaroo performer Father John Misty. Ween plays bass and Josh Tillman plays drum, and Kurt Vile pops up for a brief cameo appearance. Watch below.

Deaner & Father John Misty jam session post Ween show (those kids on the couch snuck into backstage and into the Ween dressing room, they were adorable) and yes that's Kurt Vile in there too. #ween #deanween #fatherjohnmisty #kurtvile #bonnaroo #monihamptonweentour @bonnaroo @weeninfo @kurtvile @fatherjohnmisty
