Yes, year of original recording, I neglected to say that. Unless it got hung up in the pipeline somewhere, you should have the RA by now. I haven't figured out how to make mp3 or wav that are sufficiently small yet. As for the lyrics, I have to be in a specific mood to handle lyrics, just recording songs requires a lot less brain power.
I took a look at the Norman Blake song posted by Stewie. It definitely looks like he at least modeled his chorus on The Little Red Caboose Behind The Train, which as noted in Sourdough's first post is itself a descendant of an even earlier song.
