Have you ever heard Noel Stallard doing the Father O'Brien act. He has a perfect Irish accent. He can do it and make it funny and believable...I wouldn't attempt it. And you should see/hear him doing Bush Christening...the Irish Accent makes that poem doubly enjoyable.
Yes, I love Manfred's version of Bush Christening - very funny.
As a kid my mother had a recording of Said Hanrahan and I can still hear the (unknown) male voice that did that poem and that's how I read it. It left an impression.
