Metallica

Who's got the cleanest boots in the rain-sodden, mud-slicked Vale of Avalon this weekend? Kelis, that's who.

I love the smell of Glastonbury in the morning. It smells like... OK, not quite victory. But not quite defeat either. More like bacon, coffee, marijuana, mud, sweat and beers. And, there is no getting away from it, cow shit...

Most Glastonbury headliners save their triumphant fireworks for the encore, but Arcade Fire make their own rules.

“Glastonbury! Are you seeing clearly now the rain has gone?” Guy Garvey bounds onto the Pyramid Stage, flooding the festival with avuncular game-show cheer, like that favourite teacher who always managed to get the kids on his side at school.

In a welcome blast of sunshine between downpours, an excursion to the fringe stages on the southern slopes of the Glastonbury site provides a welcome relief from the liquid mud lakes and crowd crushes around the main arenas.

Thunder, lightning and heavy downpours over Glastonbury right now. Deep joy for the 125,000 people already onsite, with more arriving every hour. It seems the gods of rock are angry. And they are not the only ones making a racket.

"Glastonbury!" beams Debbie Harry. "Nowhere else like it!" Just past midday on Friday in the Vale of Avalon, and the world’s largest voluntary refugee camp is already on the move.

Glastonbury Festival organiser Emily Eavis says she hopes the placement of Robert Plant and Jack White in consecutive slots on the Pyramid Stage on Saturday might lead to the two appearing together for a one-off collaboration. Plant plays at 5.30pm on the festival's main stage and White plays at 7.30pm, before Metallica perform their headline slot.

Iron Maiden's Bruce Dickinson has said that "Punk was rubbish". The singer made the comments to The Guardian in an interview conducted by fellow Sonisphere line-up addition Frank Turner, saying that the closest the "art establishment" ever came to embracing metal was through punk. "The reason they embraced punk was because it was rubbish and the reason they embraced rubbish was because they could control it," said Dickinson.

Michael Eavis has said that Prince became "really upset" with Glastonbury organisers over what he describes as "social media rumours".
