Hi I'm an old guy Irish/Scot folksinger, I have found a lot of "British" music has drifted around for ever in different forms. the music was generaly not written by the composer/lyricist. When the songs reached appalachia they again changed as did the accent. She Moved through the Fair is a prime example, I have it in 2/2,3/4,&6/8 the song was written down and published by Padric Colum but it existed a hundred years before(also have it in Irish galic. since the celts memorized everything and wrote almost nothing the folks claiming these song are naughty.
