I'm looking to trace the authorship of a pre1970's song called 'Culloden Moor'.   It may well be in copyright and I really want to give due credit to the person who wrote it.   The problem is that the copyright organisations have a few works published which may or may not be the same song. Some of the publishers don't have copies of the song for me to compare.   
The song lyrics start "There's a field in our homeland we call Culloden Moor, and there the flower of Scotland's youth were laid in graves so poor.....We will aye remember dark culloden moor. Copyright owner to be confirmed.

Could anybody out there familar with Scottish music help. It's a short song and sounds like it's a 20th century song. Nice melody though the words are a bit naive on the truth about the participants in the battle of Culloden and the actions that day.
