The Furey's were singing this on the LP (transl.) "1. Irish Folk Festival in Germany" the first of a series of at least 5 LPs which possibly were never sold outside of Germany. Here it is, but I have no information whether it is old (I don't think so) or who wrote it and I even don't know what the title means (personal guess: cock here means small boat). So there's room for additions.

COCK OF THE NORTH

1. Oh cock of the north with the dream in your hand,
my love has come home to this beautiful land
and he comes through the door with his eyes like the sun
and his kit's bags are full of the treasures he's won.

2. And below the old broom there's a tall luggin's tail,
a bat and a crow and the jaws of a whale,
and our kitchen is full with the smell of the sea
and all of the richness my love brings to me.

3. Come gather your treasures by our gardens and rooms,
and bring them along to the sweet little blooms
with the sun in the morning and blaze on your chest,
oh my love has come home from north by northwest.

4. And here in these beds we will lay and we'll sleep,
yes, we'll lay and we'll listen to the sounds of the deep,
and as long as the summer, we'll sleep winter long,
oh my love has come home like King Solomon's son.

5. = 1.
