Bruce Springsteen & the E Street Band were musical guests on the 2015 Saturday Night Live finale hosted by Tina Fey and Amy Poehler, and after performing two songs from the new The Ties That Bind: The River Collection box set, the show finished up with an all-hands-on-deck "Santa Claus Is Coming To Town."

The sleighbells ringing crew included not only Fey, Poehler, special guest Maya Rudulph (who starred in a highly amusing 'Bronx Beat' skit with Poehler and Fey, who played Poehler's cousin "Karen from Philly") and the entire SNL cast, but also a Beatle: Paul McCartney hopped up on stage unannounced and found his place onstage alongside Steve Van Zandt, and he answered in the affirmative when Springsteen asked if he'd been good this year.

Watch the end credits clip below, and go to Rolling Stone to catch  "Meet Me In The City" and "The Ties That Bind." Springsteen plays the Wells Fargo Center on Feb. 12.
