I had this from Sarah Maken (Tommy's mother)in her Keady kitchen in 1952. It has only two verses, ia probably a fragment of a ballad- but maybe not. At the time I felt as you do, that it should be longer, so I wrote another verse. Nowadays I love the little song as it is and no longer sing the written verse. Ironically, it was recorded some years ago (can't recall- I believe it may have been Bobby Clancy, and perhaps for Folk-Legacy?), and he used my verse, thinking it was traditional! So, maybe by now it is, but originally Sarah's version had but two verses- all it needs, really.
