Here's what I transcribed from the sound sample:

On a beautiful Sunday morning
In the hills of East Tennessee,
Pretty wild mountain flowers are bloomin'
On the grave of Dossie Lee.

And here's a quote:

Ken Orrick [lead singer and rhythm guitar player for Lost Highway Bluegrass Band] was featured in the June 2001 issue of Bluegrass Now magazine. The article, by Chris Jones, is entitled Ken Orrick - Songs that Mirror Life. The piece covers some of Ken's personal history and documents many of the events that inspired songs like Dossie Lee and Tennessee Snow.

A web search for "Dossie Lee" turns up lots of genealogy sites with records of various people named Dossie Lee. Funny, I never heard of the name Dossie before.
