Yep, that's right. Still not good enough on the venue's part for a bank holiday. It's a shame and all, but you just shorten the support bands' sets.
I caught the last three songs of Atomkraft. It was just Tony Dolan, I think the drummer from Gama Bomb, and I can't remember which bands he said the other two guys were from. To be honest, I thought they were very poor.
