Bonnaroo Lineup 2013: McCartney, Mumford Musicians Ben Lovett, Marcus Mumford and Winston Marshall of Mumford & Sons perform onstage at the 55th Annual GRAMMY Awards at Staples Center on Feb. 10, 2013 in Los Angeles, California. (AP) - There will be a British invasion of the main stage at Bonnaroo this year. Paul McCartney and Mumford & Sons are among the headliners for the 2013 Bonnaroo Music & Arts Festival in Manchester, Tenn. The four-day festival, held on a rural 700-acre farm, always features an eclectic roster, but the June 13-16 event is even more varied than usual. Returnees Tom Petty & the Heartbreakers also hold down a headliner spot. Then things get a little crazy with R&B star R. Kelly, alternative queen Bjork and Wu-Tang Clan celebrating its 20th anniversary. PHOTOS: Bonnaroo 2012 Tickets go on sale at noon EST on Saturday.
