yes I know don't wear the bands shirt u are already there why would u wear the shirt unless u brought it there then yea

haha, just do w/e, it comes naturally later on the show when you get used to being there, headbang, push people, but respect people also, you dont want to get annoying to others around you....oh yeah and the 'dont wear the bands shirt to the show you will be attenting' its so stupid, wear w/e you want, its better if you wear the bands shirt if you have one
