At an age of 21, Dave McCarn wrote "Cotton Mill Colic", a very pessimistic song that got recorded in 1930. It's about the work and living conditions of cotton mill employees which pretty much tells everything about his personal viewpoint on his workplace. Folkarchive.de's got the lyrics - for those willing to have another look at 'em. Later he formed the Yellow Jackets - the band's only song I know of so far, "Huskin' Bee", is to be found on the "Black and White Hillbilly Music"-sampler (in case you know where to find some more pls comment!) on the TRI Trikont label. In May 1931 McCarn made another four recordings and this time he had his friend Howard Long (1905-1975), a working collegue and also Yellow Jackets band member, accompanying him on guitar. Amongst these was "Bay Rum Blues" - a quite twisted description of a beaverage made from this popular hair tonic and aftershave lotion. They also made a re-recording of "Cotton Mill Colic", named "Serves 'em fine" - this time with slightly different lyrics and applying harmonica. Although these recordings didn't quite sell those days we can be lucky to still being able to listen to McCarn's heritage as an excellent harmonica player, but also as a critically thoughtful and yet very humorous person. David McCarn died on November 7, 1964, of aspirated pneumonia, resulting from cirrhosis of the liver, at the age of fifty-nine. Here's all the legal cuts I found which are relevant from a harmonica player's perspective: 
Secondly there are these little sections between the songs where DeFord speaks about all kinda harp related things such as hardware quality as well as clues his technical approach. Go check it out if you haven't done so yet - it's definitely worth it!
In 1937 he recorded two songs that have become national country standards, "Filipino Baby" and "Sparkling Brown Eyes". Although it is said that there was no doubt about Cox's authorship of "Filipino Baby", he ended up making very little from it.
George Pegram of Union Grove, NC, and Walter Parham of Leicester, NC, have been playing and singing together for many years. They appear together, and with other instrumentalists, performing for square dances all over western North Carolina, and are the annual stars of Bascom Lamar Lunsford`s Mountain Folk Music And Dance Festival held each year in Asheville, NC during the first week of August.
In the early 1920's he toured the South with Big Joe Williams as a member of the Birmingham Jug Band. In 1927 he cut several sides under his name for the Gennett label in Birmingham. In April 1930, he recorded two more songs for Columbia. These were the last sides for him as a solo artist. In December of that year he teamed up again with the Birmingham Jug Band, a group that still featured Williams on guitar and also Blind Ben Covington and recorded for OKeh. After this session he became a street singer throughout Alabama. Jaybird Coleman died of cancer at the age of 53 in Tuskegee, AL. on January 28, 1950.
