yes, definitely get in touch with the venue and see what they say. a lot of places have at least one cool person on the staff who will help you out. a few years back, I was all set to go to a Fog concert when my wallet (including i.d.) got stolen– I contacted the club to see what I could do, and they were very sympathetic and let me in with no problems. I think they appreciated being given a heads-up, rather than having me show up unannounced and try to bargain my way inside.
if the venue doesn’t want to help you, I’m sure someone here can arrange for you to be on the Dino guestlist, so ask around
