For my money, the Floyd did a set that sounded almost note-perfect. Not exactly easy to do if you haven't played with the other guys for the best part of 15 years. Much respect, etc.
The Who... I'm still shocked that they played the full version of Behind Blue Eyes - I was wondering how that high pitched wail towards the end would come out, but it sounded great to me. Notice Daltry's mike was really taped to the cable....the rodies know of his 'mike swinging' habit! Ahh.. memories!
