Watch: Bruce Springsteen and Paul McCartney Sing “Santa Claus Is Coming to Town” on SNL

Paul McCartney shows up out of the blue for 'SNL' performance

In case you missed it, last night’s Saturday Night Live was one for the books.

With Tiny Fey and Amy Poehler co-hosting and the Boss man himself, Bruce Springsteen as the musical guest, the night was already ramping up to be an incredible closer to the 2015 season. But a surprise guest appearance in the closing credits gave audiences an extra special Christmas treat, as Paul McCartney showed up out of now where while Springsteen and the E-Street band wrapped the show with “Santa Claus Is Coming to Town.”

While Springsteen’s performances earlier in the night of “The Ties That Bind,” and the live debut of “Meet Me in the City” are not available online in Canada, the surprise performance is in the player above.
