Hi Semi,
I didn't catch the PBS show. Still, they have a habit of repeating things and I'll be watching out for it next time out. That link won't open for me. A message comes up about it not being available in my area because of rights and stuff.
My link is to an archived video you can watch on demand. As for your particular area, that's another issue. The link still works for me in this area. A lot of good music in there, too. But, mostly, an in-depth look at a great songwriter and what makes him tick. (The haunt of serving Prison time.)
