I didn't see any of it when it was on, but here's a collection of song clips from the different venues. You can't go wrong by avoiding anything titled "Interstitial" and as usual, most of the artists sound a lot worse live than they do on CD. Stevie Wonder is an exception to that, of course, and strangely Jet looks like they bathed for the show. Will wonders never cease?
Also, A-Ha is still around, and they look less grizzled and weatherbeaten than Velvet Revolver. Link from Lifehacker.
