Chorus:
Oh the sands o' the shore and the waves o' the sea
When his back is turned he's a stranger tae me
He's a stranger tae me, ay, and sae let him be
For I care nae mair for him than the waves o' the sea

I aince had a sweetheart but noo I hae nane
He stole awa' ma heart but I got it back again
Ay, I got it back again, and sae let him be
For Ah care nae mair for him than the waves o' the sea

He bocht me a present o' a braw diamond ring
He thocht it wad entice me tae gang awa' wi' him
But I wisnae sae foolish as he'd ta'en me tae be
And I care nae mair for him than the waves o' the sea

Oh he is the son o' a high lord and king
And I am but the dochter o' a puir working man
Sae let him drink his wine, ay, and I'll drink ma tea
For I care nae mair for him than the waves o' the sea
