A lot of what I heard on the awards show sounded very much like rock; and these guys do other stuff:

Kenny Chesney does John Mellencamp: http://www.youtube.com/watch?v=o8PUprRC39o

Tim McGraw does Ryan Adams:  http://www.youtube.com/watch?v=Hyidx_U9k6E

If there's a show close enough and I'm free enough, I'll go just for the experience of it.
