Three years in the making, Francis Whately's film is a social and musical history of (probably) the world's greatest music festival, as told by its principal curators, Michael and Emily Eavis, and many of the key artists who've appeared there between 1970 and 2019 – Billie Eilish, Thom Yorke, Florence Welch, Dua Lipa, The Levellers, Aswad, Orbital, Fatboy Slim, Linda Lewis, Noel Gallagher, Ed O'Brien, Chris Martin, Stormzy and more.

Balancing the driving forces of social conscience and hedonism, Glastonbury has always been both a world apart and a barometer of the state of the nation. Looking at the hippie days, CND, the contribution of the travellers, dance music, Britpop, The Wall, the impact of television and the first black British solo headliner, this film takes viewers backstage and deep into the archive to reveal the forces that have driven this alternative nation between utopia and dystopia, the greatest night of your life and a muddy field in the middle of nowhere.

This is not a chronological plod through the festival's evolution so much as a thematic and story-driven exploration of the peaks and troughs, and the agonies and ecstasies, that have shaped Glastonbury's 50 years and counting.

It's been three long years, but Glastonbury Festival is back!

Lauren Laverne and Jack Saunders welcome you to the green fields of Worthy Farm, which once again will become one of the biggest music festivals on the planet. For the first time, they broadcast live from site on a Thursday night.

From their bird's-eye view over the festival at The Park, Lauren and Jack take a look at what's coming up over the weekend and investigate what the cows have been doing for the last three years. They're joined by special guests and bespoke acoustic performances.

Also joining the BBC Two gang is a Glastonbury first-timer, BBC 1Xtra's Remi Burgz, who will be exploring every corner of the festival.
