In an 1950s elementary school music book I have a text with the Cuckoo song (obviously a rendition of Peter's brook) as follows:

Oh I went to Peter's flowing stream
where the water's so good
and I heard there the cuckoo
as she sang from the wood

Ho-li-ah ho-le-rah-hi-hah ho-le-ra-cuckoo etc

After Easter come sunny days
that will melt all the snow
Then I'll marry my maiden fair
we'll be happy I know

When I've married my maiden fair
then what can I desire?
Oh, a home for her tending,
and some wood for the fire.
