This being one-half of U2 (bass and drums) plus one-half of R.E.M. (singer and guitar) doing a pretty great live version of U2's song 'One.' A few years ago I actually spent several hours trying to track down a mp3 of this performance somewhere online. I should have known just to check youTube.
I really like Michael Stipe's vocal here and the very R.E.M.-y harmonies he does with Mike Mills. But still: this is really Bono's song - it's hard to beat the original.
