Widespread Panic has been named as the closing main stage act of the Bonnaroo Music and Arts Festival, set for June 12-15 in Manchester, Tenn. The lineup was shuffled in the wake of a cancellation by the Allman Brothers Band due to health issues with founding member Gregg Allman.

"We're thrilled that Widespread is joining the Bonnaroo lineup again this year," Ashley Capps, president of A.C. Entertainment, producer of Bonnaroo with Superfly Presents, tells Billboard.biz. "It was very disappointing that the Allman Brothers had to cancel, but we feel lucky that Panic could step in. They've been at the heart and soul of Bonnaroo from its inception and their Bonnaroo sets never fail to be an extraordinary experience for the fans."

Now Jack Johnson will precede Pearl Jam on the main stage Saturday night, stepping into the slot vacated by the Allmans. Johnson, who had originally been scheduled to close the fest on Sunday, will perform beginning at sunset on Saturday, to be followed by Pearl Jam's closing main stage set.

Bonnaroo also has added Les Claypool, Chali 2na of Jurassic 5, Superdrag, What Made Milwaukee Famous, Adele, Grand Ole Party, and the Postelles to this year's festival lineup.
