Thanks JennieG. Yes. This is the version I first came across and as far as I have found, this American version is the only one of which there is a recording on the internet.
As the lyrics used by Cecilia John in Australia differ somewhat, I became interested when someone suggested that Hamish Imlach's version might have harked back to an even earlier song than the American. ie c.1900 in Britain. I wondered whether our Australian anti-war movement might have been aware of the British song, but have found no proof at this stage. Fascinating search though, so thanks again JennieG.
Cheerio, Tony
