I recall watching a program on Public Televison about 20 years ago that was a performance by Burl Ives at The Chattaqua. He was a toward the end of his touring carreer but not his performing ability.
And yes he did those songs that many people have come to detest in a group but grin warmly from the memory of them inside where no one sees. His voice was still rich and warm and flawless. His guitar work was simple and clean and suited for the parlor guitar he played.
A Martin 0-16 NY perhaps or maybe a nylon classical. But his playing was solid.

I often think I was watching a master at performing and this was a lesson in stage craft.

Did he talk to the HUAC? Yup and did he and Peter Seeger part as friends? I believe they did. And does it matter now? Maybe to some extent but not to the point where I can't forgive..
