Compare the last verse of Percy's song: And I played my guitar Through the night to the day Turn, turn, turn again And the only tune My guitar could play Was, “Oh the Cruel Rain And the Wind” to the last verse of "Oh the Cruel Wind and Rain" But the only tune that the fiddle could playWas, Oh, the wind and rainThe only tune that the fiddle could playWas, Oh, the cruel wind and the rain This a really old folk song with many variations (often called "The Two Sisters"), always with an instrument made from bones/hair of a murdered woman, which would only play sad songs. Dylan also borrowed from other folk songs - such as "She once was a true love of mine" in Girl from the North Country (also borrowed by Paul Simon). He used the tune of Lady Franklin's Lament for Bob Dylan's Dream - and also converted her 10,000 Pounds to 10,000 dollars in the final stanza. Lady Franklin was mourning her husband's death as he tried to find the Northwest Passage, with a promised reward of 10,000 Pounds. These are only a few examples. Dylan is basically a folk musician, and he has never been afraid to borrow themes, lyrics, or tunes in the finest tradition of folkies!
