OK, WAV - What do you think of a mixed session I went to a short while back in Skipton where people were playing Italian Accordions, Spanish Guitars, Greek Bouzoukis, German Concertinas, Irish Tin Whistles and Australian Didgeridoos? If you had your way the only instruments people would have been playing there would be pipe and tabor and English (but not Anglo/German) concertinas! The cittern was only popular in barber shops between the 16th and 18th centuries and now survives mainly as the German Waldzither or the Portuguese guitar so that would not qualify as an English instrument. Diversity means cross cultural boundaries should be removed, not reinforced!
