I was sure that this was in either Rise Up Singing or its predecessor, Winds of the People, but I was WRONG! WotP has more songs by Charlie Murphy than are in RUS, but not that one. It probably WAS on the mimeo'd song sheets that were the predecessor of WotP!I know (or at least I DID know) Charlie Murphy when he lived in Phila, ~1978-81 or so. He moved to Seattle, where he still lives, as far as I know. I could probably get hold of his address, email, or phone # without going through TOO many people. I also have this on vinyl, if it still plays--I was not noted for taking excellent care of my vinyl!
I can clearly remember the way the chorus sounds--it's kind of a chant, with a clearly defined meter, but mostly one tone, at least on the first couple of reps. "Diana" does go down, then it comes back up again. Then after those first 2x thru, he raises the pitch. The melody of the verse I don't think I could reproduce accurately, but probably my friend Joan, or another friend could.
Oh, I think the number of dead in the song, as Charlie wrote it, was TEN million!
If you want me to try to get hold of Charlie, email me at Marymac90@aol.com
