First of all, if you're 50, J.B. is not of your generation, she's of the one before (same as Dylan who just turned 64.)
Second, there was no such thing as "PC" in the 60's. Gosh, we even shamed our returning vets. How PC was that!! Thank God, now that we're in Vietnam II and realize we've "been fooled again," at least we're not taking it out on our troops.
Back to Joanie. Most of you probably don't remember when she won a libel suit against the cartoonist Al Capp (creator of Li'l Abner) for placing a raven-haired folk singer in his comic strip named "Little Joanie Phony." As for her voice, I can attest to what Eldartford and Eddaytona said. Steve Kuyamjian, a fellow MIT architecture student, was teaching her to play guitar, and we'd often go to hear her sing at Club 47 Mount Auburn, in Cambridge. Her voice was truly a natural wonder, the material was innocent and ageless. Find some of those early Vanguard LPs, it will be very worth your while. They leave "Diamonds and Rust" in the dust!
