sorry forgot to say that ours went:-
Goodnight Mr Moon, We will have to go and leave you,
Goodnight Mr Moon, Come again and see us soon,
And when we're asleep
Through the window pane you'll peep,
We'll wake up and call out
Good night Mr Moon.
Out along the Milky way
Is there any place like home?
Have you got a mummy dear
Like the one we have down here?
In your starry nest do you ever rest,
Goodnight Mr Moon
