"Is it a theatre?"

"I was cycling up Oxford Street, which is just for buses, and it was end to end bus! Nose to tail, all types of buses. Obviously the first one got stopped and the others just followed it blindly. Eventually the buses turned into fire engines, loads of them. By then the fire was out but it had obviously been pretty serious and I nearly ran a girl over who was crossing the road between the buses talking in her mobile saying 'Oh my god, I'm alive!' Glad to find out what all the fuss was. Great video!"
