Look back at his solo performance. Right before it starts they announce that the pictures in the background are from his book of photography. It just seemed to me like he stretched out the song into an infomercial for his photos.
I liked Sara Bareilles with Carol King, mostly because I am such a Sara Bareilles fan. If you haven't heard Sweet as Whole, listen to it sometime when you've had a bad day. It's not really a song the guys could relate to or I would post it.
