Eddie Vedder made a surprise appearance at the comedy tent before Pearl Jam’s headlining set at Bonnaroo last night. He joined his former interviewer Judd Apatow to pay tribute to the comedian’s late mentor Garry Shandling, who passed away in March, turning his jokes and writing into a song. Vedder mostly played acoustic guitar and sang while Apatow delivered the jokes, although they sang one verse together. Watch below.
