The Edge to join Muse onstage at Glasto?

The Edge is rumoured to be appearing with Muse at this year's event.

The U2 guitarist is expected to join the Devon band onstage when they bring the Pyramid Stage to a close tomorrow (Saturday) night.

U2 were originally booked to top the bill on Friday of this year's festival until they had to cancel due to their singer Bono having to undergo emergency surgery.
