I dont think sticky fingers was sold out, but it's hard to say.... Sticky fingers is a very small venue by the way. (but not as small as Logo in Hamburg and Knaack in Berlin).
Actually, i like small venues more - But i still dont understand, cause i think Pain should reffer to a bigger audience... Hypocrisy can sell out bigger places, and i think really many Hypocrisypeople like Pain as well, or atleast dont want to miss the chance to see Peter live - But I guess I'm wrong...
Age limit, dahm... But yes, i remember something about showing ID at the entrance in gothenburg... Stupid, if you ask me - i really dont understand this.
I havent heard anything about Pain supporting Nightwish.
