Here it is. The second verse is rarely, if ever, performed....Tiger

From the sheet music at Mississippi State University:


WHEN IRISH EYES ARE SMILING
Words by Chauncy Olcott and Geo. Graff, Jr.; music by Ernest R. Ball.
Copyright 1912, M. Witmark & Sons, New York

1. There's a tear in your eye,
And I'm wondering why,
For it never should be there at all.
With such pow'r 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.

CHORUS: When Irish eyes are smiling,
Sure, it's like a morn in 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.

2. For your smile is a part
Of the love in your heart,
And it makes even sunshine more bright.
Like the linnet's sweet song,
Crooning all the day long,
Comes your laughter so tender and light.
For the springtime of life
Is the sweetest of all,
There is ne'er a real care or regret;
And while springtime is ours,
Throughout all of youth's hours,
Let us smile each chance we get. CHORUS
