Pete Seeger was amazing.   I remember seeing him in concert at the Jubilee Auditorium in Edmonton in the early 70's. A friend and I were wanting to start a folk club, and we went back stage to talk to him. He spoke to us for a full hour, just talking about folk music, his respect for Canadian folk music (and how it was such a shame it wasn't honoured in it's own country the way it was honoured in others.   Such a memorable experience. I wish I would have recorded it.
