When, in recent years, the likes of the Killers, Arctic Monkeys and Kings of Leon headlined Glastonbury's Pyramid stage, nobody worried too much about what they might play. Unless said acts were going to unveil their new dubstep direction, you could be pretty certain of hearing their biggest hits, plus a few recent tracks. These newish indie bands simply didn't have enough songs to stretch past the allocated time.
This year, things are a little different. If Neil Young plays every song he's ever written he'll still be there on the Sunday night. In fact, he'll probably still be going in time to headline 2010. Let's hope he packs his wellies.
Of the headliners, Bruce Springsteen has 16 studio albums, Blur have seven (pathetic!) and the aforementioned Mr Young has recorded somewhere around 14,007 long players – we lost count during the 1980s. All of which means we can't be entirely sure what we'll hear.
What we do know is that recent sets from Young have seen him pick songs from esteemed albums as Harvest, Zuma and Tonight's the Night. We know that Chris Martin has spoken to the Boss about Glasto, no doubt stressing the importance of playing The Hits. And we know Blur have recently been airing For Tomorrow, Beetlebum and This Is a Low.
All promising signs. Now, clearly all three acts will be clicking frantically on this here music blog, looking for clues to the perfect setlist. So we thought we'd ask you what you most want to hear. Dancing in the Dark or Dry Lightning? Country House or Come Together? Heart of Gold or Here for You? Or maybe you just want to hear every song from Fork In the Road, stretched across a two-hour set with some extended bass solos? Let us know.
