Just rechecked the Richard Dyer-Bennet discography in Paul O. Jenkins fine biography of Richard Dyer-Bennet: The Last Minstrel and there is no sign that he ever recorded "The Troubadour."

Dyer-Bennet did compose "The Unfortunate Troubadour" in 1940, noting that the story was not based on personal experience.

Dyer-Bennet and Ives did collaborate in the 1940s on Burl's New York radio show entitled The Wayfaring Stranger, with Ives leading American folksongs derived from British folksongs and Dyer-Bennet leading the British versions.

Cheerily,
