I watched a good portion of that disc and I like the JJ Cale, Joe Walsh, and especially the Steve Vai parts (where Vai and 3 others stood in a line and played each others frets, fun stuff!
I am glad JJ Cale played 'After Midnight' so some of the audience could see that he wrote it (and Cocaine) even though Clapton made it popular.
I know Jeff Beck was at the concert, do you know why he was not featured on the disc? He is one of the reasons my brother bought it and I missed him too.
