Godspeed & rhythm to one Mark Lavon "Levon" Helm. On vocals in the lower video performance of the song The Weight. Mavis Staples, Pops Staples & the Staple Singers' co-vocals is a comforting thing. Harmonic. Rocks the heavenly house, so to speak. Other Band members share vocal verses, the late Rick Danko, Robbie Robertson, and Garth Hudson. Simply... The Band. Mark Lavon "Levon" Helm (May 26, 1940 – April 19, 2012), American rock multi-instrumentalist and actor, drummer and frequent lead vocalist for The Band.
