Thanks to Peter McCalister for this article on War or Peace, or Cogadh no Sith to give it the Gaelic title. There are many different versions reflecting that it was popular and widespread. Tempo of Piobaireachd over the years is always interesting. It first appears in Joseph MacDonald’s treatise (1760) marked “Allegro” (fast), and in his brother Patrick’s Collection of Highland Vocal Airs, Country Dances or Reels of the North Highlands and Western Isles (1784) “Rather Slow, Variations, Brisk.”
The Gesto version is in the new edition of Book 10 in the PS series.
