Sandy has the gist of it--not giving credit to his sources.

We have just completed a recording project using 1860s music. Much of it was written in the BC goldfields using traditional tunes. But, the authors always said, Air: Green Grow the Rashes Oh; or Tune: The Mousetrap Man.

Dylan's mistake was in never giving credit. But then neither did the folks who wrote the MTA Song,(sung by the Kingston Trio) which is a copy in tune, theme and many words of The Ship that Never returned, written between 1850 and 80.
