Tickets will be available on the door I believe, buying beforehand lets them know in advance how numbers are looking that's all. Most important thing is you turn up obviously.
Friday/Saturday isn't an option for Mega Bar obviously, facilities they can offer aren't possible in the Centenary as you will see when you get there. Big screens are important and the graphics involved just wouldn't come across as well.
Been roped in to help with some of it and I've been impressed by the plans, really hope it works for the people involved, sure it will. A good turnout for this one will surely mean more functions aimed at the fans, something that's been sadly lacking so if you can get there, get there and support it. You'll be rewarded I'm sure.
