There are several different ways of ending this one, and at least two tunes that I have come across, both of which are given below. This is my preferred version, but Daddy and Granny are sometimes sent out to bring back the little ducks and even the last little duck has been known to bring back the missing four.
Five little ducks went swimming one day,
Over the hills and far away.
Mummy Duck said: “Quack, quack, quack, quack.”
But only four little ducks came back.
Four little ducks went swimming one day
Over the hills and far away.
Mummy Duck said: “Quack, quack, quack, quack.”
But only three little ducks came back
And so on until…
But no little ducks came swimming back.
Mummy Duck went out swimming one day,
Over the hills and far away.
Mummy Duck said: “Quack, quack, quack, quack”.
And all her five little ducks came back.
