Jo Whiley and Mark Radcliffe celebrate the weekend that would have marked 50 years of the Glastonbury Festival with an inviting blend of great performances from the archives and live acoustic sets from contemporary artists. The festival, organised by Michael Eavis and his daughter Emily Eavis, takes place at Worthy Farm in Somerset. From humble beginnings in 1970, Glastonbury is now the largest greenfield music and performing arts festival in the world - with a site that is over a mile and a half in diameter. Each year, it hosts hundreds of thousands of festival-goers, who flock to see performances from the most famous names in music and immerse themselves in the vast range of performance that the festival has to offer. Tonight’s show brings viewers previously unseen or rarely shown moments, including highlights from The Rolling Stones headline set in 2013, PJ Harvey’s rocking 2004 performance shortly after the release of her sixth solo album, Uh Huh Her, the irrepressible Lizzo in an early acoustic performance in the BBC garden area, Florence & The Machine’s debut on one of the main stages in 2010, and a reminder of Stormzy’s headline set last year. The Glastonbury Experience - Friday at 8.30pm on BBC One.
