Bruce
Have you ever thought of producing a book encompasing your various findings over the years?
You must have compiled a vast amount of source material and I for one would be be grateful of the chance of conversing with you in more detail albeit via email regardings the origins of all sorts of material.
I don't know if you are aware of a project that has been started here in England called the "Village Music Project", I'm sure you could assist them greatly..
If you you want to chew the fat about any of the above, you can contact me here.. mick@prof.co.uk..
Keep up the good work
Mick
