Crazy to put Fontaines who are on a massive rise right now in with NBT and Don Broco lol - they just sold out Finsbury. I doubt people will be clamouring for their tickets in 20 years but they definitely shouldn't be alongside those 3 acts quite yet!
I'd question Green Day breaking through in 2004 as well lol - Dookie came out in 1994, 10 years before that headline slot!
KOL arguably should be in that lower category (while they won't exactly have people clamouring), they got to headline in 2009 with their two big hits coming out in like 2006 or 07?
We'll have to see if Sam Fender sticks about, he's an obvious shout.
The 1975 got there in 6 years (could have been sooner too really!), no sign of them slowing down at present either.
Why bother? There's a village nearby which is 20 mins walk away with a co-op and a few pubs.
Didcot is a bit of a dump at best - not sure why you'd bother especially during a festival you've paid £100+ for
Looking at last year's first announcement, 3rd and/or 4th acts were on T'Other. This is however s much smaller first announcement than last year, probably as it's 2 months earlier.
