Joe, "Kate's Song" is on Cathy and Dave Para's "Johnny Whistletrigger" album. It is the first of their two albums devoted to the Civil War.
When Jesse James' grave was opened for DNA testing a few years back, a funeral service was held for the reburial of the remains. Cathy and Dave sang at his funeral service! How many folk singers have something like that in their resumes!
There are no better performers of old-time music than Cathy and Dave. They have a huge number of song, old and new, that they perform wonderfully. Great harmonies and peerless musicianship.
