I would be curious to hear which cover versions you all think either equalled or surpassed the original recordings. Personally, the one that pops into my mind is B. Raitt's "Runaway" versus...uh oh...who was it, Dion? Maybe doesn't surpass it, but I'd say, is equal to it. Or maybe J. Hendrix' "All Along the Watchtower" versus You-Know-Who... Whatd'ya think?
