Bruce Springsteen's Performance of "Santa Claus Is Comin' to Town" Will Make Your Holi-Day

Bruce Springsteen and the E Street Band first covered "Santa Claus Is Coming to Town" back in 1975, and they revived the classic to close out Saturday Night Live's Christmas episode. Tina Fey and Amy Poehler hosted the show, and while they danced along to the final song, they're not the best part. Paul McCartney, or as kids these days know him, the New Artist That Kanye West Helped, jumped up on stage to sing along! Was he just hanging out at Studio 6-B that night? Fun fact: while the song was originally called "Santa Claus Is Coming to Town," Bruce's cover changed the "Coming" to "Comin'," because he's a rock star.
