Thank you all for your contributions; Paddy's memory deserved them. I'm glad to say however that I know of several songs in the Irish tradition and on Irish originated ballad sheets which use the word "transubstantiation" - mostly they are songs about young Irish men and women who have fallen in love but find an impossible impediment in their different ways of practising Christianity. As such they are contentious in Ireland. The next Inishowen [Co Donegal]International Traditional Singing Festival has the theme "Religious Songs" I will be giving a talk on songs of religious contention. It will feature recordings of Paddy Tunney and I intend to dedicate it to his memory.
