Interesting to see that the folk procees had distorted the song enough for the dog/morn non-rhyme to be established as early as 1927. But arent the ways of folk-music wonderful? herewe have a fantastically well-written and well-loved song, written in living memory, and nobody seems to know who wrote it, or even have a theory...or if there is a theory no contributors here seem to have heard it. perhapsthe author had political reasons for remaining anonymous? Intriguing, isn't it.
