got £50 tickets the first time, and they were the 2nd cheapest (cheapest being £25), the 2nd time they had raised the prices and i got £50 tickets again, but they were the cheapest avaiable that time. tbh not much in it, id get the cheapest next time, i know alot of people spend alot more for the better tickets, but im happy enough being up in the gods, they have good screens to follow it on etc...
o2 has 20,000 capacity and they sold it out, so imagine they will sell out brum.
