Hopefully not as they subbed in 2022, could The Libertines do it or are they too indie for that? Other names I was thinking of maybe someone like The Script?
Muse, if we're taking serious chat about them being in the frame. Stevie Wonder, if we're talking the "legendary" headliner everybody wants. Sam Fender if we're actually being reasonable on who we've heard so far.
If we've heard about The 1975 potentially headlining from what appears to be multiple sources, I think we would have heard about Charli XCX conversations now too, I'd have guessed.
