Michael Eavis (or someone pretending to be him) recently posted this on his Twitter account:
Michael EavisThe authenticity of the Twitter account is, however, unknown. This latest message agrees with previous rumours - the original tip-off by Mr. X on our forums, and an article in Kerrang! Magazine claiming that a 'big band' beginning with the letter M would be turning up to play a secret set at the festival.
'We have had some resistance from the black holes forming around the Park Stage, hopefully we should have that sorted before you all arrive!'
This rumour conflicts with Musewire's latest Twitter message, stating that Muse will be heading to NY tomorrow for Mastering and Partying.
