Apparently, I used to wander into the house next door when I was about 4 and bash away at the keys of the upright piano a la Cecil. The lady who lived in that house used to fume inwardly when I did this but bit her lip and didn't say anything - only in England !
A few years after that I got my first record - 'Sounds of aircraft from World War 2' (or something like that). Engine sounds of Messersmitts, Spitfires, Hurricanes, Heinkels - it had them all. It's shocking for me to think now that WW2 and the blitz was less than 20 years in the past, at that time ie. still recent history.
From that aircraft noise EP, it was an entirely logical step to collecting Mosaics and rare British jazz ( ).
