Interesting thread – though goes off topic....Song for Ireland was made famous in Ireland by the great Mary Black, and it’s sung quite a lot – still…. Generally it’s not known it was written by an English man….
And in The Foggy Dew (great rendition by Daoirí Farrell), the verse he sings mentions Perfidious Albion - Daoirí would never, ever change the words to suit himself, he has too much respect for the tradition....


oh the night fell black and the rifle's crack
made perfidious Albion reel
mid the leaded rail seven tongues of flame
did shine o're the lines of steel
by each shining blade a prayer was said
that to Ireland her sons be true
when the morning broke still the war flag shook
out its fold on the foggy dew
