Lovely tune with a beautiful simplicity. I don't think Mark wrote it, though, unless I misunderstand.
I noticed this in the comments on the Ryan's Fancy version. Credited to one "Eoghanbeg". He seems to know something about it.
"Nice to hear an Irish group singing this song by John Cameron (1822-1898). In Scottish-Gaidhlig it is usually called Chi Mi na Morbheanna. The tune to John's song was played on the pipes at President Kennedy's funeral.
The story goes that John had disembarked from the Glasgow steamer and composed his song while walking towards his Glencoe home. The view can be seen at the start of Dunach1 on YouTube. John knew William Laurie before he became a famous bagpipe player and composer."
