Paul McCartney played a surprise mini-concert for thousands of New Yorkers in midtown Manhattan from the top of the marquee of the Ed Sullivan Theater, where he was taping a performance for Late Show With David Letterman. News of the event spread via Twitter and word of mouth, and nearby street corners were closed off to accommodate fans for the 5:30 p.m. set that recalled the Beatles' famed Savile Row rooftop gig, when the Fab Four played atop the former building that housed Apple studios. In 1964, the Beatles made their U.S. television debut on The Ed Sullivan Show in the same studio Letterman inhabited.
