I wasn't being critical, merely curious. The tunes of many of his songs are pretty obvious, but since I didn't reognise the "Vigilante Man" tune, I had assumed that Woody had written it.

As Arlo said when I saw him live one time, I'm paraphrasing slightly, it was a few years ago, "the mark of a good songwriter is how skillfully he disguises the melodies that he steals".
