Turned it on right when Jagger performed the first song. Played one song with Arcade fire, a medley with the foo fighters, and an original blues song with Jeff beck that featured a kickass solo by Beck. Jagger is mad old, he kind of looks funny out there, his thighs are ridiculously skinny, but he still belts em out, and you could tell the accompanying bands were stoked to play with him.
Some real good skits in there too.
Awesome show. Best SNL I've seen in a long time.
