The beloved British band, who released their first album since 2011 in May (16), were strongly rumoured to be lined-up to play Glastonbury's iconic Pyramid Stage after an 'angry bear' symbol, previously used in their album artwork, was spotted at the event's site in Somerset, England.
On Thursday (20Oct16) Glastonbury organisers confirmed the band would be performing at next year's (17) event by tweeting a picture of the symbol laid out in front of the Pyramid Stage with the caption, "Friday 23 June 2017 @Radiohead".
The picture and message was subsequently retweeted on the band's official Twitter account.
Radiohead's Glastonbury slot will be their first U.K. festival appearance since they played a secret gig at the festival in 2011. The Thom Yorke fronted group previously headlined the festival in 1997 and 2003.
Others rumoured to be in line for headline slots include French dance pioneers Daft Punk and legendary British indie rockers The Stone Roses.
Kings Of Leon have also expressed an interest in playing Glastonbury, with their drummer Nathan Followill saying in an interview with BBC Radio 1 he would text Glastonbury boss Michael Eavis to try and get on the bill.
