The Highwayman supergroup - lyric explanations?

I’ve really enjoyed Johhny Cash et al singing on the Highwayman collection.

They seem to be pretty meaningful lyrics too.
Is there a discussion of these anywhere? (SDMB fans are invited to dive in!)

Bump. (And a nitpick) The group was Highwaymen Makes sense since there were four of them. Their first album was Highwayman as was their second (with a 2 appended).
