Google just found me The Dark Island Waltz with comment below the melody settings.
e.g.
"There is further controversy about this song. Alan Bell wrote words to what he believed was a traditional tune. Also, Stewart Ross of Inverness, Scotland wrote a very well known version of the song in 1963, after being assured that the tune was traditional. There were at least 4 English lyrics that were written in the 60's to versions of the tune. The Ross words were written to a very different version of the tune and are not a straight fit to the accordian tune.
Note: (From Stewart Ross' son) "There were no other words to the tune before my father's were written. David Silver wrote a set of lyrics in response to my father's appearing first - and has been paid and very usually credited for both lyrical versions. The tune had been played on the Scottish music circuit before being formally copyrighted and had earlier titles including Dr. MacKay's Farewell to Creagorry and Dr. McInnes's farewell to South Uist."
