One of my treasured possessions as a teen was The Joan Baez Songbook (which I still have) and I always remember the editor's exhortation in the preface that we should not try to sing like Joan (as if any of us could!) because that wasn't why she had presented her songs, and that we must try to find our own way into them as she had. What good advice - those words have stayed with me ever since, as have the lovely photographs of Joan and her guitar out in an open field.
