This kind of posts is what made Leaks & Ken19 run away from here. They are workers of the music industry, where there are a lot of confidentiality in the contracts. They can hint, they can say something the day before the annoucement, buy if people ask if XXXXX band is going to perform you can create them trouble and maybe risk their jobs os a relative/friend job, and one day they decide to run away when the feel pressured.
Yeah looks like Elbow before Snow Patrol sunday.
From the formatting, my guess would be Maribou State are the only once announced so far to be headlining the tent (makes most sense to me that'd be on Sunday opposite Snow Patrol) ... perhaps Clean Bandit second in tent, maybe same day and before Maribou State.
PSB I'd imagine early evening in the tent and Sigrid around 3rd/4th on Obelisk.
