No one can match the power of the real Rolling Stones (Keef 4 life), but Saturday night Mick Jagger's new bands--Foo Fighters and Arcade Fire--came pretty damn close. Jagger led the two in a medley of Stones classics, starting with Arcade Fire, who (along with the Strokes' Nikolai Fraiture on bass) blasted through the riff-tastic '60s jangle "The Last Time." Foo Fighters and Jagger did a medley of "19th Nervous Breakdown" and "It's Only Rock 'n Roll (But I Like It)." And Jagger's ol' pal Jeff Beck also showed up for a rendition of a politically-themed new song "Tea Party."

Arcade Fire returned to join Jagger and the SNL cast to perform "She's a Rainbow" and "Ruby Tuesday" in honor of Kristen Wiig, who is leaving the show. It was definitely an "Awwwwww" moment.

As for Jagger, he wasn't too shabby as the host--his opening monologue had its moments--but the man still shakes it even at 68. It's only rock n' roll, and it appears that he still really, really likes it.
