Since this thread began by mentioning Richard Hayward. it's worth saying that his singing of songs, and his interest in them represented a much broader tradition than is now thought of as Ulster "protestant" music. The sectarian end of that tradition is not all that there is (as Liam's brother, Dan, has pointed out) I wrote a brief article in the Befast Telegraph which is available at http://www.belfasttelegraph.co.uk/today/aug20/Features/bop.ncml It points out the broad range of identifiably "catholic" and "protestant" songs that exists. It is neither definitive or complete.
