Burl Ives was a legend for a reason - he sold tons of records when you still had to be at least modestly talented to get a legitimate contract. He was a great singer and fine accompanist for himself on guitar and banjo.

FWIW, he and Pete Seeger reconciled near the end of Ives' life, and sang together a few times then.

I am quite sure that Ives regretted his testimony for the effect it had, his patriotic sense of duty notwithstanding.
