Old Forbes gave me the only version of this story I heard in Jamaica.
In Trowbridge, JAFL 9: 284–285, the song and the incident of the three
drops of blood occur, but the king is “King Tonga” and there is no
beast transformation. The husband is lost by letting a little dog kiss
him, as in number 105 and in Parsons, Andros Island, 55, 59, not by his
wife’s burning the skin as in this version.
For the song at night as a means of recognition see number 74.
See Grimm 88, The Singing Soaring Lark; Bolte u. Polívka 2: 229–273.
