The lyrics for "When Irish Eyes Are Smiling" were written by two Americans Chauncey Olcott, and George Graff. The words were set to the music of Earnest Ball and was used in a production of "The Isle of Dreams". The music was published in 1912.

When Irish Eyes Are Smiling

When Irish eyes are smiling,
Sure it's like a morning spring.
In the lilt of Irish laughter,
You can hear the angels sing.
When Irish hearts are happy,
All the world seems bright and gay.
And when Irish eyes are smiling,
Sure, they steal your heart away.

There's a tear in your eye,
and I'm wondering why,
For it never should be there at all.
With such power in your smile,
sure a stone you'd beguile,
So there's never a teardrop should fall.
When your sweet lilting laughter's like some fairy song,
And your eyes twinkle bright as can be,
You should laugh all the while and all other times smile,
And now smile a smile for me.

When Irish eyes are smiling,
Sure it's like a morning spring.
In the lilt of Irish laughter,
You can hear the angels sing.
When Irish hearts are happy,
All the world seems bright and gay.
And when Irish eyes are smiling,
Sure, they steal your heart away.
