Reading the thread on 'bird without a gall' reminds me of something in Joe Heaney's version of this riddle song. In the verse mentioning 'A sparrow's horn, a priest unborn' one Melcassadek' (spelling approximate) is named as the priest. Who is this person?. And what does 'priest unborn' mean?. This has puzzled me for years. Can anyone help? Joe sings it beautifully by the way. Burl.
