Five Finger Death Punch have been teasing a special guest for their new album and during their performance at the 2013 Revolver Golden Gods ceremony they finally unveiled that none other than the "Metal God" himself, Rob Halford, was appearing on their new single, 'Lift Me Up.' The cane-wielding vocalist took the stage to perform alongside Ivan Moody, delivering the hard-hitting single with aplomb. The performance can be seen above.

Five Finger Death Punch also performed their own track, 'Burn It Down,' to kick off the set and they finished out by bringing their "other Rob" -- Zombie, that is, along with his guitarist sidekick John 5, for a performance of the White Zombie classic, 'Thunderkiss 65.'
