CD Baby—a great resource—has a generous sound sample, from which I transcribed this:

TO HEAR DOC WATSON PLAY (excerpt)
Si Kahn

1. I lost my mother when I was young, but I had Doc and Rosa Lee.
I'd cry along to that vinyl record when they sang "Your Long Journey."

CHORUS: If I had a gold watch and chain, I would pawn them any day.
I'd walk across the Blue Ridge Mountains to hear Doc Watson play,
Just to hear Doc Watson play.

2. The harder falls the early frost, the brighter shine the autumn leaves.
The words of those we've loved and lost bring us comfort while we grieve.

3. When our singing time is past, and all our best is left behind,
The songs we loved will live and last, like thoughts of spring in the wintertime.

4. …?
