It's not exactly making people panic if "promoters promised today there would be “more to come”", I actually think that statement has the opposite effect, i.e. it was pretty stupid to say that.
I'm just completely shocked that there's actually so many people buying these expensive tickets. I mean it's not like BJ are the first act there or like there are no bands ever playing there, people KNOW that others only cost 30 pounds and they are still willing to pay more than that for BJ!? I just don't get it.
