You are describing it just as it was, Elmer. Well said. I thought Joan did a super job harmonizing to Bob's melody lines, and she was teriffically adaptable to the changes, of which there were many. Bob tends to be unpredictable. There are some great photos of those duets, and you can feel the magic even there, without hearing the music or the voices.

The juxtaposition of Joan's very pure-toned voice with Bob's rough, Guthrie-esque-cum-Ramblin'JackElliot approach was interesting and curiously effective, in my opinion. It beats hell of out listening to duets such as Diana Ross and Lionel Ritchie (who are technically both darned good singers, but...they do pure schlock).
