This is how my wife remembers it:

Sunday dawn, Cock-a-doodle-do, he was gone, Cock-a-doodle-do, and I thought my heart would break.

He has feathers blue and bright, Cock-a-doodle-do, when he sings Cock-a-doodle-do, flaps his wings, Cock-a-doodle-do, he is such a pretty sight.

France and Spain I travelled through, Cock-a-doodle-do, and to Germany I flew, Cock-a-doodle-do, no bird there, Cock-a-doodle-do, not in England or Peru.

So kind friends both far and near, Cock-a-doodle-do, to my pleading heart give ear, Cock-a-doodle-do, find my pet Cock-a-doodle-do, don't forget Cock-a-doodle-do, Bring me back my rooster dear.
