I'm pretty sure that when Bowie played, the coverage agreement wasn't written into it in the same way it now is.
Not sure about when the Stones played, but even if it was - it's the Stones.
once they show off Anyma and their potential new stage, that day will likely be packed.
I am told this Chappell girl is very hot right now and she is very likely co-headlining with Charli, that day could do well. And we still have 4 more to go, one of them likely Post Malone who also sells out.
I don’t share your pessimsm
