I remember reading an article on what follows. With the article there was a photo of pete kissing Burl on the top of the head. I figured that if Pete could do this ... it was something that I needed to try to understand.
From Wikipedia on Burl Ives
Ives was identified in the 1950 pamphlet Red Channels and blacklisted as an entertainer with supposed Communist ties. In 1952, he cooperated with the House Un-American Activities Committee (HUAC) and agreed to testify, fearful of losing his source of income. Ives' statement to the HUAC ended his blacklisting, allowing him to continue acting in movies, but it also led to a bitter rift between Ives and many folk singers, including Pete Seeger, who accused Ives of naming names and betraying the cause of cultural and political freedom to save his own career. Forty-one years later, Ives, by then using a wheelchair, reunited with Seeger during a benefit concert in New York City, having reconciled years earlier. They sang "Blue Tail Fly" together.
