Let's not forget Joan Baez's sister, Mimi (1945-2001). Interestingly, the girls' father is the noted physicist Albert Baez (1912-2007). I remember a physics teacher in high school showing us an instructional film made by one Albert Baez. We were surprised to hear that he was Joan's father. We hadn't heard of him, but we sure had heard of her. This was around 1965.
Joan and Mimi sing a lovely version of Donovan's "Catch the Wind." Speaking of Donovan, here he and Joan collaborate on another unforgettable 'sixties tune, "Colours." Finally, Mimi, her husband Richard, and Pete Seeger in Pack Up Your Sorrows.
