The official announcement saw plenty of brilliant acts confirmed for the June event, and while we’re definitely excited to see the likes of FKA Twigs and Mark Ronson perform, we can’t help but wonder who the special guests might be.
Ian Brown's band are favourites to perform
Perhaps, we’re reading into it too much, but the fact the poster states ‘guests’ seems to suggest the act will be a band, and the bookies agree.
Paddy Power have stated that Stone Roses, who pulled out of their headline slot back in 1995, are currently the favourites to perform.
Other acts to make their shortlist include Taylor Swift - who’ll be in town with her ‘1989’ tour the week Glasto takes place - and Blur, who are already scheduled to headline Isle of Wight Festival in early June.
