Paul McCartney And Taylor Swift Sing ‘Shake It Off’ At ‘SNL 40’ After-Party

After Sunday’s three-and-a-half-hour television special, 40 years’ worth of “Saturday Night Live” dignitaries left 30 Rock and piled into New York City’s Plaza Hotel for an after-party that reportedly stretched into 4 a.m. The bacchanalia found Paul McCartney fulfilling bandleader duties as Taylor Swift, Jimmy Fallon and Dan Aykroyd joined him for a rendition of The Beatles’ “I Saw Her Standing There” and Swift stuck around for a “Shake It Off” (!!!) collaboration.
