Anybody remember:

Humphrey and the Dumptrucks was a terrific jug-bluegrass band out of Saskatoon in the late-'60s. They lasted through the mid-'70s or so;

Diana Marcovitz was a quirky songwriter from Montreal who was based out of New York City for a while and then disappeared;

Alexandre Zelkine, a guitar-playing baritone from Russia via France and Canada who sang folk songs from all over the world in the '60s and early-'70s.
