Paul McCartney and Dave Grohl ED PARK • 9:57 p.m. | Ladies and Gentlemen, The Beatle! Paul McCartney performs “I Saw Her Standing There” with Dave Grohl. Jon: Glad Paul is doing “I Saw Her Standing There” - I was afraid he’d be dour. Dave: He was always the “Clean Up After a Legendary Rap Performance” Beatle. Jon: Many legendary nights with Rakim in the late 80s. But Dave Grohl: what does he signify? He’s Zelig. His career is one long episode of “Punk’d.” No one on the corner has swagger like Paul.   —NYT liveblogs the Grammies
