O'Farrell was a piper not a dancer. His first collection contains 4 Scots tunes, the rest are, except for one, Irish with titles in English and Gaelic. Where is the invader? The one is "Cummalum", which is a member of a family widespread over the British Isles. It has been suggested that the family descends from a 17th century tune, obviously Scots, 'Up wi' Aley, Aley', but first found in an English publication. [A corrected version of the badly printed first publication, 1685, is among the ballad tunes given in ABC on my website.]
