I am thinking it was filmed in the late 1970s and used to air on PBS into the 1980s. It was a regular show … half hour I think.
The show had one host who would feature different musical instruments or styles in each episode. One example I recall was where he did a segment on the dulcimer and played it a bit.
The host had a knack for being unintentionally quirky. I think he wore flannel shirts. He had these kinda horn rimmed glasses, and he somehow looked a bit disheveled all the time.
He was a very soft spoken fellow.
I used to watch it, not to learn about music, but to make fun of the guy.
Thanks!
