Really shows how tastes differ. I can see how those 3 would be a HUGE set of headliners, but I cannot see a way that I would be happy to pay to see them, not my taste at all. I think that 2020 was the ONLY time that could have happened too.
There's a local (North East) band called BigFatBig who are acting as both support and backing band on Beth's tour next year. Assuming that's still a case for her festival dates would be great if they got a slot of their own as well.
