Nobody has at any point said otherwise. All anyone has said is that it seems unlikely because of the tour schedule. Doesn’t mean it won’t happen. Doesn’t mean it’s not possible. Just that in my opinion there would be more obvious options.
Nope, it is possible, but it would need a lot of sorting out, which is why I (and others) are saying it would be logistically tricky. Tour managers for stadium shows don't like tricky, they like smooth, easy, simple.
Because one is significantly larger than the other, one has more restrictive insurance regulations, one doesn't halt a multi million pound show if there's an issue and they don't make it. Green day can do it, I just don't think they will.
No-one has said it's logistically impossible, just that it would be hard.
"Far greater distances are travelled by acts on consecutive tour dates, all around the world, every week. It's really not an issue."
Please can you point out a few recent stadium shows going from the UK to Ireland with no days in between? These are the ones I was able to find, but maybe I'm missing a whole bunch who go direct from UK to Ireland without a day inbetween.
