Thanks, Vole. I like the Janis song, but that is not the one I am looking for. The song is "You Better Get It While You Can," by the late, great Steve Goodman. I don't have my transcription with me at the moment, but here is some of it:

I remember when I met Carl Martin, musta been a dozen years ago.
This wise old gent was gray and bent, but his eyes had a firey glow.
He was born April Fool's day, 1906 near Big Stone Gap, VA.
And he could play a little fiddle and some blused guitar that he picked up along the way.
But, Jethro, once he put his hands on the mandolin, he lit up just like a Christmas tree.
Along with Ted Bogan and Howard Armstrong, they were the best string band I ever did see.

I can manage the basic chord structure, but there are some licks that I would like to see up close and slowly (or in tablature) so I can try to replicate them for a more authentic sound. Maybe someone out there who knows of this song can hear it out?

I'll post the full lyrics when I am back at my "home" computer where I have that file.
