Lee DeWyze Performs 'Simple Man' on American Idol

Also slinging his acoustic guitar was Mt. Prospect, Illinois' Lee DeWyze, who said the lyrics to Lynyrd Skynyrd's "Simple Man" — a tune he has frequently performed at karaoke bars with his hometown pals — have always spoken to him.

Starting out solo acoustic, DeWyze didn't change up the arrangement of the classic-rock ballad too much but still managed to put his patented bar-band-crooner stamp on the tune.

After asking him why he chose the song — Lee explained that it just makes him happy — Cowell said Lee picked well. "I don't think you won round one; I think you just crushed the other two," Cowell said. Comparing him to a "little baby lamb" when they first met him, Ellen busted out another of her bizarre metaphors and said Lee's blossomed into a carefree impala.
