Bruce Springsteen and the E Street Band were the special musical guests on Saturday Night Live last weekend (December 19) and as the show signed off for the night, Bruce brought in a special guest of his own.

The Boss had sent out tweets to fans to let them know he was appearing on the show and that there there would be a surprise or two. He told everyone to keep watching for the closing credits. Now we know why! Sir Paul McCartney dropped by to help perform “Santa Claus is Comin’ To Town”. Earlier in the evening, Springsteen and the band played tunes from their recent release “The Ties That Bind: The River Collection”.
