Coldplay will be joined onstage by The Bee Gees' Barry Gibb during their Glastonbury headline set this summer, according to reports.

"ChrisMartin, singer was delighted to be asked to headline again but told Michael Eavis, Glastonbury organiser he wanted to bring some friends along, too.

Barry had already been asked to perform but didn't have time to perfect a full set with his touring band . . . As soon as Chris got wind he asked Barry if he wanted to come on stage with Coldplay."

"Barry agreed straight away. The band are putting a Bee Gees medley together cramming in all of their classics.

It's going to be really special. There are likely to be a few other surprise guests on the night too, which are still to be decided."

Glastonbury 2016 will take place at Worthy Farm over the week of June 22-26.
