Speaking of folk music and Judy Collins, here's one I've never seen, with Judy singing a duet with Joan Baez and Joan's "Diamonds and Rust." The sound is so-so, but not bad, considering. They hint at a recording in the beginning, but I'm not sure what album this is from. I'll have to google Newport Folk Fest 09, I guess.
And speaking of folk music and Joan Baez, whom I've had a mad crush on since the '60s, when I was much too young for her, this is her and her sister, the late Mimi Baez-Farina. If you're looking for inspiration, google Mimi Farina some time. Don't stop at the
Wiki link, though; keep going. She was an amazing woman, as famous in some circles as her more publicly well-known sister.
