It's not what was requested, but there is this old sentimental song with nearly the same title:

THAT'S WHAT IRELAND MEANS TO ME
Words, Joe Goodwin. Music, James F. Hanley. 1917.

VERSE: You ask me why I always talk of Erin
And why I love that island in the sea.
Just listen and I'll try my best to tell you
What dear old Ireland means to me.

CHORUS: What raindrops mean to flowers while they're blooming,
What dollies mean to little girls at play,
What moonlight means to lovers honeymooning,
What home sweet home means when you're far away,
What gladness means to hearts bogged down in sorrow,
What music means to those who cannot see,
The love that first you knew when your mother smiled at you,
That's what Ireland means to me.

[The Virtual Gramophone has two recordings: one by Henry Burr (1917) and one by Harry McClaskey (1918).]
