The year (which I didn't refer to) was 1968, by the way
Shortly afterwards I and the friends I mentioned went on a prolonged drinking spree at the insistence of Nigel Denver who was appearing at MSG later - Nigel was the Last Man Standing that night
Also (it all seemed to have happened in 1968), Alex Campbell did one of his technicolour yawns over a n MSG audience member
I seem to remember a singer/banjo player (Frank Duffy) ran a non-guest club evening there - at the time it was one of the largest audiences I had ever sung in front of (I sang 'The Patriot Game' for my sins)
Next time Ewan and Peggy appeared there they were put up at a Guest House not far from the beautiful Elizabethan 'Shambles' which later escaped demolishment by being lifted high in the air by a crane and lowered down later onto the roof of a newly-built underground car park (or maybe that was the effects of bigel's pub-crawl)
