The Tennessean is reporting some rumors and rumblings of who will perform at the 2010 Bonnaroo Music & Art Festival in Manchester, TN.

Flaming Lips — Frontman Wayne Coyne told Spinner that the band was performing two late-night sets at this year’s Bonnaroo — one of which being their take on Pink Floyd’s Dark Side of the Moon. Dave Matthews Band — The band has left a conspicuous gap in their tour schedule from June 9–14, and whaddya know — Bonnaroo takes place June 10–13. They last appeared at the festival in 2005. Wale - The acclaimed rapper includes a June 10 date at Bonnaroo on a recent tour itinerary. Paul Simon — LiveDaily reports that he’ll be on the bill this year, then proceeds to get our hopes wildly high by speculating that Paul McCartney might be coming, as well. GWAR(?) — Twitter and message boards are rife with claims that Gwar frontman Oderus Urungus announced that the costumed metal marauders would be at Bonnaroo this year, but we’ve yet to see a confirmed report or hear audio of this announcement. One thing’s for sure — it’d be an unusual addition.

The annual festival, which brings in some of the biggest musicians in the world, will take place June 10-13, 2010. The official lineup for Bonnaroo 2010 will be announced February 9th. Official Bonnaroo Website
