Woody Guthrie took John Hardy Was A Desperate Little Man from the Carter Family and wrote Tom Joad with characters and a plot that he took from the movie version of The Grapes of Wrath that was taken from the book that was written by John Steinbeck.

And now Johnny Irion, the great-nephew of John Steinbeck, is married to Sarah Lee Guthrie, the granddaughter of Woody Guthrie, who was a friend of Pete Seeger who knows both Martin Carthy and Bob Dylan personally.

Small world, ain't it?
