Glastonbury Festival 2011 has added Mumford & Sons and Fleet Foxes to its line-up. The two bands join headliners U2, Coldplay and Beyonce at Worthy Farm in Pilton, Somerset, between June 24-26.

And the Glastonbury bill is bulging by the minute, with extra bands added to the three-day festival, including The Chemical Brothers, Crystal Castles, Primal Scream, Anna Calvi, BB King and Friendly Fires.

Rumours abound that the Foo Fighters, who are yet to play the famous fest, has recently released a new album and a string of European Tour Dates with a Glastonbury-shaped slot just perfect for the night of Saturday 25th June.

At a recent secret gig in Camden, London, the band performed a marathon three-hour set with plenty of new material as well as old numbers. A Radio One DJ announced that there were to be some appearances at UK festivals during the festival season. So could Glastonbury be one of them? Here’s hoping!

Tickets for this year’s event sold out in around four hours after going on sale in October.

The scheduling of Primal Scream, headlining the Other Stage on Friday at the same time as U2 headlining at the Pyramid, has put a few noses out of joint.

Primal Scream’s last appearance at the Festival in 2005, when they played the Pyramid on Sunday between Garbage and headliners Basement Jaxx was not without controversy as they overran their allotted time, offended everyone and Bobby Gillespie had to be carried off stage by security when he refused to leave. 

Mumford and Sons will be playing just beforehand.

The London-based nu-folk group have come a long way since their last Glastonbury appearance in 2008 when they occupied the BBC Introducing Stage in the Park, a mere six months or so after they’d formed. Last year they played a packed out John Peel tent in an early afternoon slot.

Chemical Brothers, as always, are expected to turn in a good show at Pilton. Along with other stage headliners, Fleet Foxes and Friendly Fires, they’re in familiar territory, having played on Michael Eavis’ farm before.

Blues legend BB King should be an awesome addition to the line-up, which is shaping up indeed.
