From the sheet music at the National Library of Australia:


O SING TO ME THE AULD SCOTCH SANGS
Words by The Rev. Dr. Bethune, music by J. F. Leeson, no date, ca. 1890-99.

O sing to me the auld Scotch sangs, i' the braid Scottish tongue,
The sangs my father wish’d to hear, the sangs my mither sung,
When she sat beside my cradle or croon'd me on her knee,
And I wadna sleep, she sang sae sweet the auld Scotch sangs to me.
And I wadna sleep, she sang sae sweet the auld Scotch sangs to me.

Sing ony o' the auld Scotch sangs, the blithesome or the sad.
They mak' me smile when I am wae, and greet when I am glad.
My heart goes back to auld Scotland; the saut tear dims my e'e;
And the Scotch blood leaps in a' my veins, as ye sing the sangs to me.
And the Scotch blood leaps in a' my veins, as ye sing the sangs to me.

Sing on; sing mair o' thae auld sangs, for ilka ane can tell
O' joy or sorrow i' the past where mem'ry lo'es to dwell.
Tho' hair grow gray and limbs grow auld, until the day I dee,
I'll bless the Scottish tongue that sings the auld Scotch sangs to me.
I'll bless the Scottish tongue that sings the auld Scotch sangs to me.
