Will.i.am, David Cook, Harry Connick, Jr. entertain on 'American Idol'

The best four finalists ever on “American Idol” are going to be chopped to three tonight — and they remind us right off the bat about how good they are with a rousing version of Beyonce's “Crazy in Love.“

It's pure energy flying around the stage, with strong vocals from everyone. Rare that a group sing meshes as well as this; even the choreography is inspired.

Singing “Laying Me Low" -- jaunty beat, interesting lyrics. Total pro, always good to hear him.
