Liverpool St was the nearest tube and probably one of the few big enough for us to smuggle 600 people onto without arousing too much suspicion. This went seamlessly until we all got onto the platform, and waited at the back for the longest 7 minutes of my life. The guard on duty was desperately trying to get people to move up the platform, and everyone was doing their best to stay at the back (the driver hears less if you are at the back of the train). Eventually the train arrived, and we all squeezed on. Filling over four carriages, the party had officially turned into a beast.
The train pulled out of Liverpool St and the refreshments were brought out of hiding. It took us a couple of stops to set up the sound system, but the party had begun.
