It is an incorrect attribution in the Sorcha's link. The poem is attributed to Peter Cape with music by Phil Garland. See the notes to Garland's 'Colonial Yesterdays' Kiwi LP SLC-137. Evidently, its original title was 'The Stable Boy' and Garland came by it from a collection of Elsie Locke. Great song. Even though it is from NZ, I'm using it in a workshop on strine stuff at the Top Half Festival next weekend.
