This may not be the right one, but...

From the sheet music at the National Library of Australia:

THE SUNSHINE OF YOUR SMILE
Words by Leonard Cooke, music by Lilian Ray
Published in London by Francis, Day and Hunter in 1913.

1. Dear face that holds so sweet a smile for me,
Were you not mine, how dark the world would be!
I know no light above that could replace
Love's radiant sunshine in your dear, dear face.

CHORUS: Give me your smile, the love-light in your eyes,
Life could not hold a fairer Paradise!
Give me the right to love you all the while,
My world for ever, the sunshine of your smile!

2. Shadows may fall upon the land and sea,
Sunshine from all the world may hidden be;
But I shall see no cloud across the sun;
Your smile shall light my life, till life is done! CHORUS
