During their headlining Coachella set last Friday, the Black Keys were joined by pal John Fogerty in paying tribute to the late Levon Helm of The Band. Taking the stage with the Ohio blues rockers, Fogerty led the group in an emotional version of "The Weight," The Band's 1968 classic. The Creedence Clearwater Revival frontman traded vocals with the Keys' Dan Auerbach, making the performance a joyous celebration of Helm's life and career. Helm passed away in New York on April 19th after a long battle with throat cancer. He was 71.
