The popularity of this legendary Somerset shindig shows no sign of waning as the years pass, with tickets for the weekend's music and mayhem selling out in a matter of hours. Michael Eavis's Worthy Farm now having become a temporary city that's home to over 100,000 people, live first-night performances come from headliners Oasis and on the Other stage, the Chemical Brothers, along with Kings of Leon, Franz Ferdinand, Ojos de Brujo, the Bees, Michael Franti and Spearhead, Goldfrapp and PJ Harvey.
Jo Whiley, Mark Radcliffe, John Peel, Phill Jupitus and Lauren Laverne take viewers through the pick of today's events, while Glastonbury's very own "grumpy old men" offer their opinions. Plus acoustic performances, special guests and an insight into some of the more obscure corners of the three-day event. Coverage continues with Fabio and Grooverider on Radio 1 until 3am.

Music: Glastonbury 2004 7.00pm BBC3/11.35pm BBC2
How many music festivals can boast both James Brown and Wagner on the bill? Only Glastonbury, which features acts from all corners of the music scene, including opera for the first time this year. In an inspired piece of programming, the English National Opera will perform excerpts from Ride of the Valkyries to a (probably bemused) crowd on Sunday. But the pop music's good, too. So, what takes your fancy? Paul McCartney playing Beatles hits? Morrissey? Oasis? Or perhaps something more cutting-edge - Muse, Scissor Sisters or Franz Ferdinand? They're all here, along with too many others to namecheck. The beauty of it is, you don't have to fork out £12 or set up camp in Somerset to enjoy it all; you can cherry-pick the highlights over the next few nights on BBC2 and BBC3. OK, so you won't be getting the famously magical Glasto vibe, but BBC3's Edith Bowman and Colin Murray will do their best to make it a memorable experience nonetheless. (David Butcher)
