This is 'hypothetically' a fantastic idea, I think it extremely unlikely I would be able to attend this imaginary event simply because I have a young family I cannot just drop at a moments notice and I'm not rolling in enough cash to just jump on a train/plane (it's taken me 12mths to save for this tour). So live stream and DVD sub gift would be awesome.
But if by some chance it came about that it ever happened and I was in a position to attend I would hope that the band would not consider me less of a fan simply because A. I am to young to have been a shameless fan girl in the 80s (I've been hanging off the bands every sound since I was a little girl but one cannot account for the time your own conception!) and B. Have only recently had the disposable income to afford a subscription (no i'm not less committed, just less well off than some). But I'm sure they wouldn't, I do not think that would be in the spirit of U2 and everything they stand for.
If I had a choice over the where, then of course maybe the Civic/Wulfrun in Wolves (never going to happen I know, but it's practically in my back yard ) small but big enough to get plenty of happy Zootops in, I would enjoy getting together with so many Zootops as much as I would enjoy seeing the band.
If I had a choice over the when then give me a few weeks notice and rough idea of location, so I can financially and practically prepare (no reason we couldn't be given a specific location then bus us to the real location if secrecy is an issue, depending on numbers of course).
If I had a choice of playlist, I would take anything just for the opportunity, but I'd give my right arm to see Gloria and some super rarities.
Ticket allocation, my heart says let me bring my sister who is as big a fan as any of us but simply does not have the means pay a subscription fee, but my head says well at some point this turns into a stadium gig so you have to stop somewhere, I would want a much more intimate setting. Only way round that would be to do a lot in many locations, which is highly unlikely.
Last of all, I just want the boys and as many Zootops as possible to sign my t-shirt so I will have something to mark an unforgettable experience, love this big U2 family
