As always, rumours spread like wildfire around Glastonbury.
And one topic has festival-goers particularly interested - who will be playing a secret set this year.
After a fallow year, the festival is back but there are always secrets to be found beyond the lineup poster.
And everyone on the festival site is convinced a fan favourite British band will be taking to the stage.
You may have guessed it - Foals.
A lot of people were surprised - and disappointed - when Foals' name didn't feature on the main lineup poster.
The Oxford indie-rockers, widely seen as one of the best British bands right now, are having a huge year after releasing their fifth studio album, Everything Not Saved Will Be Lost.
That album was followed by a huge tour, leading many to think that they were surely lined up for a Glastonbury performance, but as yet they have not been announced.
Many have suggested the four-piece could be the 'TBA' act which starts at 18:15 on The Park Stage tomorrow (June 29).
Whether the rumours are true - who can say? But we are on site and will bring you the latest when we find out anything more.
