Yeah, doesn't look like Beni has exclusive clout these days. I remember when I first started going to festivals it was held in regard as a proper jewel in the festival season crown.
My friend and I almost went the year you're referring to (2017) and the closest I ever actually came was having tickets in 2020. Got them early so for about £45 they had Liam Gallagher, Vampire Weekend, Foals, Khalid, The Libertines, Two Door Cinema Club, The Lumineers and The Hives. Could not believe they had all that for basically the price of a gig ticket.
