Jim, Paul, Dingo, Giovanni,
Thanks to all. I don't believe there is a question members can ask without getting back helpful answers!!

(Agree with you Giovanni on the knowledge shared and wonderful performance).
Great to get a couple of more videos, Dingo, and to learn the musician's name, Paul.
Jim, I shared my original video with a friend and he asked about what he thought was such a "subtle use of bellows." My friend had a more discerning eye than I did. I didn't notice Mr. Paats was performing on a Roland "V" accordion. It
was well done.
I'm glad I asked the question. Much appreciated. ~Bob
