Roger:
Never worry about talking too much. Your comments are welcome and as you say, we all learn from each other. When our nations seek to control what we learn, that is the time for us to sound off in spite of those who wish to remain blind in the face of censorship and state terror. We must remember that informed folk musicians have always been the fear of dictators, as seen in the murder of Victor Hara.
Good man yerself Roger, best wishes
Larry
