Call the Marquee a grotty dive. I spent a few happy years there making those oil/water filters and repairing the 'hi-fi' 2 x 807s in each amplifier. Got in free if I made a few filters. Then moved to a smaller club in one of the pubs in Croydon, when they told us to shut because of the noise and overcrowding we had Cream, Hendrix and Edgar Broughton for our last three nights and that was noisy! Turned the place into a folk club after that.
