Clapton's set with santana. Real good stuff, gets you moving.
Randolf and his pedal steel were great too, first time I've ever watched someone play a pedal steel proper.
I myself was pretty impressed by John Mayer's chops. And as usual, there's that comedic rush when you see the huge ass beard and the pimping hat, and then suddenly, the thought "BILLY GIBBONS!!!" hits you like a freight train. Kinda disappointed that he didn't play Pearly Gates on his set though, that thing I daresay, is the BEST sounding LP I've ever heard.
