Just ran across this post. I was AT that show, took my wife for Valentines Day. I tell that story at least once a year to someone. Here's how it went down. Connick announced at the beginning of the show that we had a special guest with us that night. I was thinking Frank Sinatra. So he plays about an hour and 15 or so and by then we had all forgotten about it. It had a been a really good show up to that point. Connick comes back center stage at that point and invites his special guest, "Ladies and Gentlemen, Jimmy Page!" I was absolutely floored, so was everyone else, there was a kind of incredulous gasp and then a growing applause as Page comes out of the audience up front. Literally took the guitarists instrument who offered it almost as an homage, with a mock prayer hands and bow. A cool moment. two numbers, the Bb thing he mentions in the interview and then one more. He was clearly struggling with the guitar but he gave a super effort and stayed with the band the whole time. Then he was off the stage, running out the back of the hall. Of course, at this point, the show wasn't over and I'm thinking "OK Connick, what'll you do to top that??" But he DID top it, he absolutely SLAYED the rest of the set. It may have been the best display of pure musical showmanship I've ever seen. A fantastic show.
