Who was that Guest Singer in American Idol 2007?

A guy who sang a Jazz or was it Blues? Song... One part of his lyrics goes "You know this guy, you know that guy." Who is it? And what is the name of that song?

  1. i thought it was Jon Bon-Jovi
  2. Quincy Jones? I haven't watched all of the episodes, but he would fit your jazz/blues description.
  3. wow i had the same exact question and I've just spent over an hour scouring the web for the answer. it's called "Lost Without U" by Robin Thicke.
