I'm not sure it's quite the first booking for next year's Glastonbury, but one band has already been signed up.
There's a background: the Rabbit Hole Stage was struggling to find someone prepared to play their headline slot against The Stones on Saturday this year, so Hamish Guerrini made up a silly name - The Railing Stains - and put that down for the slot.
The trouble is, nobody at the festival realised it was a joke, and the band name started to appear in promotional literature.
They even got picked as a "top thing to see".
Still, no harm done, eh? It's not like there's a real Railing Stains.
Except there is. They're a Brighton-based Stones tribute, and naturally they were surprised and excited to discover they were playing Glastonbury.
They tried to find out how to get in, but failed. The Argus captures the happy ending:
After hearing of the band’s disappointment through The Argus, Mr Guerrini added: “When I found out we tried to get in touch, it would have been great to have them play.That's, of course, assuming Eavis doesn't poach them for the Pyramid stage.
But unfortunately it didn’t happen.
“As a way of making it up to them I would love to book them for next year on the Rabbit Hole stage.”
