Quite right, a Mháirtín. It is a Scots Gaelic song in Strathspey time. What they call "purt a' béul" - in Irish "port an bhéil" i.e. "Mouth music" very often nonsense lyrics put to a dance tune and meant to accompany dancing rather than be listened to for its own sake. Though having said that, modern singers have performed it as a "tour de force" of musical tongue twisting. The same sort of thing occurs in Spanish song e.g. "Virgen de Amor" where the speed of delivery can be quite astounding in the mouth of a skilled performer. Welsh has at least one song where increase in speed is the essence of the performance, the song being "Cyfri'r Geifr."
