Adam Lambert
His second song is a pick from Simon Fuller. A blues song called "A Change Is Gonna Come". (A nod to the messiah?)
LOL. He is sooooo freakin' over the top. His face looks like the sad half of a theater mask. 
Silly and scream-filled, but the judges will gush all over it.
Randy: Amazing R&B classic. The real reason you're here--you can sing your face off. Unbelievable.
Kara: That might be your best performance. (blah, blah, blah.)
Paula: That was best I've ever heard you sing! Ever, ever, ever! You look like a superstar up there. I'm in awe of your talent.
Simon: Adam, all I say after that is you're 100% back in the game.
