The Foo Fighters went on the season finale of Saturday Night Live to back up Mick Jagger for one of his performances on the weekend.

Watch here

 Jagger also had The Arcade Fire and Jeff Beck with him. You have to think that the SNL afterparty would be pretty awesome with all of those people hanging out. The SNL afterparties are already pretty legendary. But this one might be right up there.

We've now found out that the performance on TV from Jagger & the Foo wasn't the only one. They played the after party as well. Jagger teamed up with "Chevy Metal" Which is the Foos Classic Rock cover band. See it below.

 "Bitch"

 "Miss You"

It would appear that Mick wasn't the only one that did some covers with the Foo. SNL cast members did too....

 "Bad Reputation" with Amy Poehler

"I Love Rock And Roll" Feat. SNL's Kristen Wiig, Jason Sudeikis & Andy Samberg
