Foo Fighters played at the after party, and Jagger unexpectedly performed with them.

“He sang live karaoke,” Hader said. “Suddenly the song ‘Bitch’ came on and we were like “Oh. That’s Mick Jagger singing. Oh my God.’”

The Jagger-hosted episode also featured an emotional sendoff for Bridesmaids star Kristen Wiig, who will not be returning as an SNL castmember next season. Hader said Wiig’s final episode left the cast teary eyed.

“That was pretty rough,” Hader said. “We were doing a sketch before the last one, and suddenly it hits you: ‘This is our last sketch together.’”
