I saw Sabbath at Ozzfest 2001, and then Ozzy headlined solo in 2002. For an old guy who can barely walk, he sure manages to kick a lot of ass onstage.
I'm not sure what I think of VR, though. I picked up the CD, and while it's certainly good, something just doesn't feel right about it. Weiland's vocals just don't strike me as being 100% suited to Slash's guitar. I think VR would have been much better off enlisting the vocal talent of Sebastian Bach, because Bach kicks unholy amounts of ass.
