First Alnighter I attend in around 1984. Remember the external building facade had scaffolding and one of the punters in the queue decided to climb the scaffolding much to the annoyance to the police. Fond memories.
Out of curiosity, what is going estimate of price for the original MM? Brought my original at the 100 club all nighter off the DJ spinning records on the night. Brings back nice memories when I play it.
