I am seeking the melody for this poem from "A Child's Garden of Verses".
I have heard the first line of music (right up the music scale) from 2 different people (USA and Trinidad). I'm not interested in contemporary versions, but rather, a traditional one, probably from the 20's or 30's. The words are:

THE SWING
Robert Louis Stevenson

HOW do you like to go up in a swing,
Up in the air so blue?
Oh, I do think it the pleasantest thing
Ever a child can do!

Up in the air and over the wall,
Till I can see so wide,
Rivers and trees and cattle and all
Over the countryside—

Till I look down on the garden green,
Down on the roof so brown—
Up in the air I go flying again,
Up in the air and down!


Many thanks for any help.
