Casey Abrams sends a jolt through 'American Idol'

Casey Abrams up last on "American Idol" in Austin, singing "I Don't Need No Doctor," he's instantly better than I thought based on his schtick of carrying a mouth organ thing around.

High-energy, fun, scatting all over the place, and it all hangs together well. "YES" all the judges say together, he's totally like a shock of electricity. 

Yeah, it'll be neat seeing him again. A bit crazy maybe, but in a good way.
