SWEETHEART DARLIN'
(Words, Gus Kahn. Music, Herbert Stothart. 1933)

VERSE: My father was Irish, my mother was English, but the Irish has the upper hand in me;
And, speakin' of Irish people and things, how'd you like an Irish melody?

CHORUS: There's a light in your eyes, sweetheart darlin',
And it makes all the world fair and bright,
Like the light in the skies, sweetheart darlin',
When the mornin' steals out of the night.
'Tis lovelight a-shinin' for someone.
Sure I'm wond'ring just who it could be, my darlin'.
There's a light in your eyes, sweetheart darlin'.
Tell me, darlin', it's shinin' for me.

REPEAT CHORUS

[Sung by Marion Davies in "Peg o' My Heart." Also recorded by Morton Downey, Annette Hanshaw, and Denis O'Brien.]
