The saddest thing of all was when he performed the bluegrass version of Jump, and looked so insanely happy just to be on stage. That's on YouTube as well... and it's just cringe-inducing. Though I'll admit, hearing a banjo player rip through an Eddie Van Halen solo was quite entertaining - in a completely surreal sort of way.
DLR doing Bluegrass? I surfed into something about that on VH1 the other day and thought that I didn't hear right.
There is a mellow rendition of Jump by the 80s band Aztec Camera that's pretty good, in a mellow sort of way. Acoustic, and all that.
