It’s nearly time for one of the biggest musical events of the year - as 135,000 people pack into Worthy Farm for the Glastonbury Festival.
They’ll see headliners The 1975, Olivia Rodrigo and Neil Young, along with hundreds of other acts across over 100 stages.
But looking at the schedule on the official website, music fans will see numerous timeslots with ‘TBA’ next to them - with no indication of who will be playing.
It could be a global megastar, or some busker from down the road on an acoustic guitar. Such is the joy of the festival.
There are some big gaps to be filled - on Friday there’s 11.30am on the Woodsies Stage, 4.55pm on the Pyramid Stage, and 8.30pm on the BBC Introducing Stage.
On Saturday, expect plenty of interest about who exactly ‘Patchwork’ are - third on the Pyramid Stage bill. Meanwhile there will be surprises for prime spots on the Park Stage at 7.30pm and the Shangri-la Stage at midnight.
On Sunday, those opting to go to the BBC Introducing Stage at 8.30pm could be in for a treat (or not).
The bookies reckon they have a fair idea of who will be playing the secret slots - here are their 11 favourites, according to online bookmaker, Betway.
Mike Reading, spokesperson at Betway, said: “Glastonbury is known for its surprise secret slots, with the likes of Lady Gaga, Foo Fighters, and George Ezra popping up unannounced over the years. Everyone’s talking about what acts could surprise the crowds at Worthy Farm this year, and with not long to go until the gates open, Glastonbury organisers still have it tightly under wraps.”

9. Pitbull - 20/1
Glastonbury has been embracing rap more frequently in recent year, so what about a set from American superstar rapper Pitbull. He's in the middle of a European tour so wouldn't have far to travel. He's priced at 20/1. | Getty Images

10. Radiohead - 20/1
Radiohead haven't played live as a band since August 1, 2018, but fans reckon that the creation of a new legal entity, 'RHEUK25 LLP', is a sign that they are about to get back together for a new album, tour or both. They are priced at 20/1 to start that journey at the world's most famous festival. | AFP via Getty Images

11. Green Day - 30/1
One of the stranger statistics about Glastonbury is that Green Day have never played the festival. They are priced at 30/1 to make that right this year. | Getty Images
