When awesome Green Day side project Foxboro Hot Tubs played a tiny club show we went all the way to London on the off chance of getting tickets, successfully got them and then had to wait 13 hours until the show at 1am. Mostly in a pub across the road since they wouldn't allow queuing until the evening, but that's a long time to wait while always keeping an eye out for a queue starting so we wouldn't miss it and it was FREEZING weather so the actual queuing part was quite brutal. Totally worth it, right at the front and the best show ever.

I can't think of much else I'd queue that long for. I don't even queue that long for normal Green Day shows, they're my favourite band but getting there 6-8 hours early always gets us a good spot.
