Absolutely riveting television.
I thought the Knack and Tommy Tutone both kicked ass with their hits, however I thought both their cover tunes were sub-par. The Knack covering Jet could have been a good fit, but if you can't hit a note, don't cover the tune. Tutone is awesome, but covering Blink-182? Gag. Never-the-less, they were the only true "bands" last night.
That wasn't the Motels. That was Martha Davis with a bunch of 23 year olds backing her. It's a shame, because the original Motels were a pretty solid new wave band that got overshadowed by the marketing of Martha by MTV. That being said, her Nora Jones cover was great. Speed up the song, give it some balls...she just can't bring it, though. She was overshadowed by her band, and her vocals were too high in the mix.
Haddaway...wow. His hit has been solidified as a SNL parody of dance music, but I thought his voice has survived pretty well. I thought his cover of Brittney's "Toxic" blew her version away, and I'm sure it will be on I-tunes in a week. That appearance may revive his carreer.
Vanila Ice. Nice Eminem imitation, and clearly good enough to sway the brain-dead music fans of today.
All-in-all, a hugely enjoyable hour of TV.
