Jack Johnson to Replace Mumford & Sons at Bonnaroo Festival

Billboard is reporting that Jack Johnson has been announced as the last minute replacement for Mumford & Sons as the Saturday Night headliner. Mumford & Sons' Ted Dwane is recovering from brain surgery he underwent earlier this week.

Johnson said that he got the call on Thursday and said "I've got a lot of lyrics and chords to relearn by Saturday night...I was here to play the first Bonnaroo and it is a very special festival to my band. We are excited to hit the stage again."

Calls were made to both Johnson and Darius Rucker but since Johnson was already on the grounds, the gig went to him. He was there for a press conference in support of his upcoming album 'From Here To Now To You.' Rucker is scheduled to be in Baltimore Saturday night.

Mumford & Sons released a statement saying Dwane's surgery went well and he's well on the way to recovery. However, in order to give him time to recover they deceided against perfoming. They also were forced to cancel their performance next week on Colorado's Telluride Festival.

The statement reads 'If we could've we would've, you know that about us...We trust that you can respect our collective desire to encourage Ted to make a full recovery, and that this is based purely on the medical advice we have received.'
