Thanks, Bill. Any more on this parody version. To put in date context, I can state definitively having heard it sung by Pete Sayers at the first Cambridge Folk Festival in 1965. He was an English country singer who had travelled much in the US, ('[he]was a bluegrass musician and the first Englishman to appear at the Grand Ole Opry.': from the wikipedia entry on his daughter Goldie Sayers, who is a distinguished javelin thrower), where I suspect he would have learned this version. Can anyone confirm this, I wonder?
