Source for notated version : - O'Gallagher [O'Neill]. The only 'O'Gallagher' O'Neill references in his Irish Minstrels and Musicians (1913) was a Timothy O'Gallagher, a piper from Clofert, who "played most excellently" for an exhibition in Ireland in the 1860's. He is probably not O'Neill's source for the tune. A rather more likely source is Charles O'Gallagher, a member with O'Neill of the Chicago Irish Music Club in the first decade of the 20th century.
