Taylor Swift

Taylor Swift performs during the Capital FM Jingle Bell Ball 2014 held at The O2 Arena in London on Dec. 7, 2014.

From the looks of it, Sunday night's Saturday Night Live 40th Anniversary celebration wrapped up with a jam session for the ages, including Taylor Swift, Paul McCartney, Jimmy Fallon, Prince, Haim, Bill Murray and more in an all-star band. The set notably included Swift's "Shake It Off" and the Beatles' "I Saw Her Standing There."
