Yes it was him. He left in the middle of the encore. I didn't get a chance to get up to him because he was with, what appeared to be, two females (a blonde and a brunette about late 20's/early 30s). He was in between both of them. No one really seemed to make a big deal that he was on the balcony b/c not that many people approached him. He appeared to be having a good-time.
Bob, what did you think about the show. I was amazaed that he played the sweetest perfection...wished he played Blue dress, though.
