I would be surprised if Woody said that, given that Woody deliberately wrote lyrics to old tunes all the time, in the spirit of Joe Hill, so that people could pick up a broadside with lyrics about a current event, and sing them--

At any rate, I don't have a great deal of sympathy for Behan,whose idea seemed to be that once he took something from the public domain, no one else could use it--sort of saying that"The Folk Process Stops Here"--
