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 this year's event, to be held June 13-16, is even more varied than usual.

Returnees Tom Petty & the Heartbreakers also hold down a headliner spot. R. Kelly, Bjork, Wu-Tang Clan, Wilco, Pretty Lights, The Lumineers, The National, Kendrick Lamar, Nas and ZZ Top also top the list announced Tuesday by "Weird" Al Yankovic via Bonnaroo's YouTube channel.

Tickets will go on sale at noon Eastern Standard Time on Saturday.
