Francy - you say that Dylan has denied borrowing from other sources. Could you please give an example - an article, a book, etc. where he has denied doing such a thing.   I'm not saying you are wrong, it is just that I've never heard him say such a thing nor have I heard it discussed before this forum.   It has never been a secret that Dylan used other sources for his songs, much like his idol Woody Guthrie. It was never a secret because it was no big deal - that was the folk tradition that Dylan grew out of.
