With Glastonbury 2013 just a few breaths away, festival fever has started to grip the world as the highlight of the music calendar looms on the horizon like the big, burling legend that it is. But almost as exciting as the headliners is the talk around who could perform another infamous secret set.
Previous secret surprise sets at Glasto have seen the likes of Radiohead, Pulp and The Dead Weather often overshadowing all other performances at Worthy Farm.
Come with us, as we take a look through the bands who may or may not show up unannounced, and discuss the rumours, probability and awesomeness of what suprises Glastonbury 2013 may have in store...
Prince
It just wouldn't be Glastonbury without a Prince rumour. With a rockier new sound and having expressed an urge to play more intimate venues, a surprise slot on a smaller stage might be the perfect chance for 'His Royal Badness' to get back to basics. Plus he's in Europe for a gig in Stockholm a couple of days before, so who knows?
Muse
The Devonshire space rockers have been owning the summer so far with their stadium-destroying madness. Sadly, they're playing in Italy on 28 and 29 June so it could prove a bit of a stretch - unless they finally hire a spaceship.
David Bowie
The Thin White Duke appears adamant not to tour his blinding comeback 'The Next Day', with his guitarist Earl Slick further denying all rumours this week. However amid rumours that his live band have been rehearsing in New York, it wouldn't be the first time this year that Bowie shocked the world.
Kings of Leon
With a new boxset out, a new album on the horizon and UK dates in Manchester, London and Birmingham either side of Glastonbury, it could be the perfect opportunity for the 'Four Kicks' rockers to debut some of their 'youthful' new material. They're in Switzerland on the 29 June, but have 28 and 30 free - so who knows?
Queens of the Stone Age
Josh Homme and co have just released one of the best rock records of the year so far. It would be a shame for them to not tear a hole in Glastonbury. Mr Homme also appears on the upcoming Arctic Monkeys' album, AM. He could at least get up on stage with them.
The National
They seized the day when they took to the Glasto stage back in 2010. Now, with latest LP Trouble Will Find Me, they're back and better than ever. They've also announced a last-minute show at London's Roundhouse on Wednesday 26 June - just a few days before Glastonbury. Coincidence, eh?
Blur
With no British dates confirmed for 2013 and the teasing of recording new material, could Glasto welcome Damon Albarn and co back into its hallowed fields? Maybe. There's a big gap in their schedule between Turkey on 21 June and Poland on 3 July.
One Direction
Yep, you heard. There have even been rumours of 1D making an appearance. We're with Nick Grimshaw on this one - no thanks.
Justin Timberlake
Set to preview the Legends of the Summer tour with Jay Z at July's Wireless Festival, could JT bring his Suit and Tie to Glasto?
Daft Punk
The French duo would be insane not to capitalise on the crazy success of Random Access Memories. The bookies have put their faith in Daft Punk making an appearance - but can you see it? Nile Rodgers is already there. The least we can hope for is for Pharrell to show up too and show Glasto why 'Get Lucky' is the anthem of the summer.
MGMT
They're in the country and have an album coming out. Just sayin'....
Radiohead
Thom Yorke usually finds a way to show up at Glasto somehow. Speaking to Zane Lowe about whether or not Atoms for Peace would be there this year, Yorke coyly replied: "Yes, no, maybe, not as the whole unit, maybe as a broken part of the unit. I've got to get in somehow for free, so...We are planning to go to Glastonbury, and so we have got to do something, but it might not be that."
The Strokes
With no promotion for their fifth album Comedown Machine, it seems pretty certain that the New Yorkers won't be there. The world seems to have forgotten that the record even came out in the first place.
Kanye West
Glasto has been waiting for a storming set from Yeezy for a long time. With new album Yeezus dividing opinion and no tour dates announced, Glasto might just get a little bit harder, better, faster, stronger.
Emeli Sande
As inevitable as Glastonbury mud, she always shows up somewhere, somehow. What a fitting name she has - like sand, she gets everywhere.
