I was at this show with my now wife. I was on my way to LA to buy tix for their show there when I heard that Yes was playing at the Bowl on Chirs' birthday!! During "Amazing Grace" Chris tried to come out to the crowd, thought better of it and went back to the stage.
Unfortunatley, the seats we had were near the very back, but this was Yes, so I didn't care! I remember people behind us talking loudly during a peaceful part (Soon?), so I turned around and told them: "You know, I paid good money to hear Jon Anderson sing and not you talk!" ~~WOOSH~~ we could hear every note from then on!
I also remember that during the ovation after Roundabout, I was standing and pointing my one index finger toward Heaven and waving with the other hand (as in "you guys are number one")...and I SWEAR Jon pointed right at me and then pointed to Heaven and then waved, all with his right hand. I felt that we connected for that moment...moment...moment.
During Holy Lamb just when Jon was singing "like a light thats lost upon the stage" the spotlight blew up!
