The story of the beast-husband transformed by means of a song is very common in Jamaica. It occurs in Milne-Home, 42–45, and Jekyll, 73–77; 132–135.
Compare Junod, 246–253; Parsons, Andros Island, 39–43 and references in note 1.
In Parsons’s Andros Island variants, the transformed beast is the wife (compare number 84) and has the form of a bird, as in Jekyll’s two versions, one of which, 132–135, ends with the “Yonec” story. In all the versions I heard, and in Milne-Home, the wooer is a bull.
