Wasn't gonna deal with this, but I'll try.
Just barely in my teens got to hear they young Liam Clancy live lots. What a clean, fine tenor. Still 1 of my faves. Leadbelly, Pete S. all felt to be faves at times. Ed McCurdy for a bit. Later in life ran into lots I liked. John Hartford, Danny Barnes, Steve Earle. There's a singer-songwriter in the Austin area named John Clay: he has a non-vibrato tone that makes you pay attention.

But my favorite male folksinger is special. In my late teens I was on a long car trip with my dad(about 12 hrs) thru the aftermath of a monster blizzard. Only time I remember ever being alone with him in the car. Never noted for his musicality, yet he sang "Henry Martin" & nothing tops that sound in my heart. Tw
