'American Idol': Casey Abrams Sings 'I Don't Need No Doctor' By Ray Charles

Casey Abrams wowed the judges on Wednesday night's 'American Idol' in Austin and proved he don't need no singing doctor.

The 19-year old from Idyllwild, California goofed off, jammed out on his melodica and admitted to looking like movie star Seth Rogen. But Casey was all business as he belted out Ray Charles' 'I Don't Need No Doctor' and wowed judges Randy Jackson, Jennifer Lopez and Steven Tyler -- on whose behalf the 'Idol' producers found it necessary to issue a fake apology at the beginning of the show.
