Yeah - I'm aware of the main reasons for them being discounted (albeit not the 'paid a lot for exclusivity' element). Just spitballin' other potential names in the frame.
Green Day are doing Download and they have paid a lot for exclusivity.
It was also announced this week that they are headlining Tinderbox on the Saturday of Glastonbury weekend and they are already booked to headline Tons of Rock on the Thursday and a show in Luxemburg on the Monday. They haven't done three shows in a row since pre Covid. Not happening.
