Tho' only a poor kazoo player I do find other instrument threads fascinating (even if I don't understand them!).
When I lived in Sarf Lunnon (South London) in the '70s there was a junk/antique/second hand shop called Reuben's nearby which like many of its kind never seemed to be open. It had a few dusty instruments amongst the clutter one could see throught the dirty windows which also had a yellowing poster advertising "Reuben's Banjo Museum" with no address. This has always intrigued me. Do any UK 'Catters know whether this museum still (ever?) exists. Seemed a strange place to have it. Peckham ain't Nashville!
