A lot was spent on Hank Williams Junior. Too much I think. The segment seems to have been about sons and daughters of the well-known artists.

The George Jones part was especially moving, I thought.

I think Burns was right to point out the conservative aspects of country music,
a tendency to adhere to a format or style. Nashville's influence was pervasive over the commercialization of Country. Perhaps because of Chet Atkins and Steve Sholes.

I didn't see the Bob Wills part but he never wanted to be thought of as a Country
musician. He was enamored of the swing bands of the time.

I think some attention could be paid to the guitar and fiddle as major components of
country music. Also the steel guitar (both pedal and standup). Especially the "geetar".
The banjo prevalent in traditional folk music seems to have played a minor role until Earl Scruggs and Don Reno. There was the comic relief of Uncle Dave, Stringbean and Brother Oswald as well as perhaps Mac Wiseman.

Country Music is a marketing genre such as Race Records or R and B or Rock. The limitations that it has seems predicated on recording sales. Even the Outlaws were a recording gimmick despite the talents of Nelson and Jennings.

The music business as we know it has changed. It was true in early Sixties until the merchants figured it out. I think we're seeing the same thing now. Who can predict where it's going? It may go the way of Capitalism. It works for a few but not the many.
