As a trio, yeah, U2-Coldplay-Beyonce is the kind of bill stadiums would like to have. Even if I still am puzzled why U2 decided to plonk Glastonbury in the middle of a US leg of their 360 Tour and just fly Maryland to Somerset to Michigan. It just sounds like a great way to exhaust yourself and the fact they were all out of sync with each other for the opening song feels like the kind of mistake you make with such jetlag.
Speaking of U2, meanwhile, Adam Clayton said the following about their plans on an Italian radio station:
"We’re doing some more work this month, at the end of November, and in the beginning of December we going to be back in the studio. I think by the middle of next year, we’ll have a very good idea of how many songs we have to finish, and when we want to release it. And then a tour will follow on from that."
So I think this feels more likely of U2 being active on the road in 2026 rather than being a possibility this year. At one point I saw an account claiming U2 were going to be at Glastonbury this year, but the possibility seems to be receding.
Still played stadiums and headlined festivals. So they could do a job, even if I agree a 4th time doing Glastonbury as a Pyramid headliner isn't really as exciting as a first time head.
I still feel like they're a Plan B or C if something else doesn't happen though. Although I'm assuming the rumour they turned down Download Festival but are still planning to tour Europe hints they are up to something.
