Veteran rockers The Rolling Stones wrapped up their North American tour on Monday night (24Jun13) with their last show before a landmark performance at Britain's Glastonbury festival. The band ended the 50 & Counting trek with a gig in Washington, D.C. after two months on the road taking in cities including Los Angeles, Las Vegas and Chicago, Illinois, as well as a handful of dates in Canada. Monday night's show at the Verizon Center included a special appearance by former Stones star Mick Taylor, while Lenny Kravitz and pop stars One Direction were among the famous faces in the crowd. However, frontman Sir Mick Jagger expressed his disappointment not to see U.S. President Barack Obama in the audience with a thinly-veiled joke about the telephone surveillance scandal surrounding America's National Security Agency, declaring, "I don't think President Obama is here tonight... But I'm sure he's listening in." The stars of One Direction took a break from their ongoing U.S. tour to see the Stones perform, and they were given the chance to go backstage and meet veteran rocker Ronnie Wood, who posted a picture of the moment on his Twitter.com page, writing, "Great to see you tonight (Niall Horan) & (Harry Styles) - glad you enjoyed the show!" Horan added, "Unbelievable experience tonight... massive thanks to... (Ronnie Wood) and The Rolling Stones a great gig... and for being so nice tonight." The Rolling Stones will now head back to their native Britain ahead of a huge headlining gig at Glastonbury festival over the weekend (29-30Jun13).
