Joe, that midi threw me- sounds like an old Civil War tune - can't think of the name (old age disease).

The score given by Cohen on p. 373 of "Long Steel Rail" sounds right- this was taken from the Delmore Brothers. Was this the same as the Carters' release of 1929?

Nice version by Vernie Westfall at American Memory, "Voices from the Dust Bowl."
Also Thompson, Judd and Wright, same collection.
