Jack Johnson headlined the Gorge Amphitheater on Saturday night and was joined by a pair of friends including Amos Lee and Pearl Jam’s Eddie Vedder who helped the guitarist through a cover of The Beatles’ “Rocky Raccoon.” Vedder has previously played Johnson’s Kokua Festival in Hawaii and sat in with him during the event. The two also collaborated at Bonnaroo in 2008 where both Johnson and Pearl Jam were performing.

Vedder also helped Johnson out with the ALS Ice Bucket Challenge, dumping the water on the singer-songwriter in a video posted to his Facebook.
