Just listened to the sound clips at the Folk Legacy site. "Heights of Alma", as recorded there, sounds like a variant of a song I've heard with a chorus that goes "Briton's sons will long remember, the glorious twentieth of Sep-tem-ber, we caused the Russians to surrender, on the Heights of Alma". Both versions are apparently about a battle that took place during the Crimean war.

I find myself wondering "what makes this an Irish song?" I suppose the answer is that it was collected from Irish sources. And there may well have been Irishmen among the ranks of the combatants. But it doesn't sound very Irish to me.

Perhaps I need to listen to the entire song, to see if an Irish point of view emerges.
