Thanks Peace. It was a guy singing with a guitar. Standard folk song type stuff. Quite angry, sort of updated Woody Guthrie style. Someone loaned me an album with it on about 1978 or so. I can remember the tune very clearly but not most of the the words or the name of the artiste. Obviously it was an American singer.

I was in CA a few weeks ago and it reminded me of the song.

Thanks. JK.
