NASHVILLE: 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, Tennessee.

The four-day festival, held on a rural 700-acre (283-hectare) 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. Wilco, Pretty Lights, The Lumineers, The National, The xx, Kendrick Lamar, A$AP Rocky, Nas and ZZ Top also top the list announced on Tuesday via Bonnaroo's YouTube channel.

Tickets go on sale at noon EST on Saturday.

McCartney, the former Beatle and recent frontman of a brief collaboration with the surviving members of Nirvana, will be making his first appearance at the event.

Mumford & Sons, fresh off its album of the year win at the Grammy Awards, return to Bonnaroo after a memorable 2011 second-stage performance that stretched more than an hour, drew friends Old Crow Medicine Show and had fans hanging off fences to get a better view.

Other top-of-the-list performers include Macklemore & Ryan Lewis, Animal Collective, Daniel Tosh, David Byrne & St. Vincent, Passion Pit and Grizzly Bear.

The festival hosts more than 120 acts. More will be announced later.

There are a few curiosities on the list. Glam-punk Billy Idol and Odd Future member and mystery man Earl Sweatshirt are scheduled to perform. Jim James will host a Soul SuperJam with John Oates, Zigaboo Modeliste of the Meters and the Preservation Hall Jazz Band.

Fans of roots rock, Americana and folk-leaning acoustic music will have more than Mumford and The Lumineers to focus on. Also scheduled to perform are Dwight Yoakam, Jason Isbell & The 400 Unit, John Fullbright, Of Monsters and Men, Calexico, JD McPherson, Father John Misty and The Tallest Man on Earth.
