This is from Margaret McGuinness's Memoir (1973) - it's almost the same as the lyric posted above:

CHORUS:
Ireland, Ireland, though I am over the sea,
Erin, my country, at night I am dreaming of thee,
Dear little isle of the west, sweet spot of memories blest,
Land of the bog and the shamrock, oh, how I long to be there.
