It was a' for our rightfu' King,
We left fair Scotland's strand;
It was a' for our rightfu' King
We e'er saw Irish land,
My dear;
We e'er saw Irish land.
Now a' is done that men can do,
And a' is done in vain;
My love and native land farewell,
For I maun cross the main,
My dear;
For I maun cross the main.
He turn'd him right and round about
Upon the Irish shore;
And gae his bridle-reins a shake,
With adieu for evermore,
My dear;
With adieu for evermore.
The sodger from the wars returns,
The sailor frae the main;
But I hae parted frae my love,
Never to meet again,
My dear;
Never to meet again.
When day is gane, and night is come,
And a' folk bound to sleep;
I think on him that's far awa',
The lee-lang night, and weep,
My dear;
The lee-lang night, and weep.
