of course i can't prove that my story is real and i am not the maker of those tracks, but i wouldn't remember about this forum as a place to inquire if the stuff on youtube didn't sound authentic. some parts of the song on my link blatantly remind of famous tunes like 'Haughs O' Cromdale' and i still believe much of the stuff by that guy might be borrowed from the authentic repertoire. in another track he sent to me there 'Bleacher lassie o' Kelvinhaugh' is evidently recognizable. https://vocaroo.com/15qpRPJJrlPt
