I was at the Greek Theater show. I think it is the one they recorded for CD/DVD, because I remember the awful squeak towards the end of Wakeman's Close to the Edge pipe organ solo.
Tony Levin was sight-reading music. I remember on Close to the Edge, he had several music stands (2-to-4) lined up in front of him, shoulder-to-shoulder, with the music all spread out. He nailed that tune.
Being a jazz fusion player, Levin's style was different than Squire's, but I enjoyed it. He definitely saved the tour. I can hear how the phone call from Bruford went: "Tony, we have a problem...I need a favor..."

I was told that Berlin was reading music from a teleprompter. After the first Greek Theatre show I had an opportunity to talk to Bruford, and asked him about this. He chuckled (in his inimitable accent) "Telly-prompter? Nothing as complicated as that. Only pencil and and paper, I'm afraid!"

Saw them in L.A. and they DID announce (somehow) that Levin was sick and Berlin was in. My wife and I had a conversation about the issue just before the show.
