The Cuckoo sat in the old pear-tree,
Cuckoo!
Raining or snowing, nought cared he.
Cuckoo!
Cuckoo, cuckoo, nought cared he.

The Cuckoo flew over a housetop high.
Cuckoo!
"Dear, are you at home, for here am I?
Cuckoo!
Cuckoo, cuckoo, here am I."

"I dare not open the door to you.
Cuckoo!
Perhaps you are not the right cuckoo?
Cuckoo!
Cuckoo, cukoo, the right Cuckoo!"

"I am the right Cuckoo, the proper one.
Cuckoo!
For I am my father's only son,
Cuckoo!
Cuckoo, cuckoo, his only son."

"If you are your father's only son -
Cuckoo!
The bobbin pull tightly,
Come through the door lightly -
Cuckoo!

"If you are your father's only son -
Cuckoo!
It must be you, the only one -
Cuckoo, cuckoo, my own Cuckoo!
Cuckoo!"
