I'm sure you'll be delighted to know that storytelling in Irish as well as in Irish English is still there. I suggest that you have a look at the website of
http://www.storytellersofireland.org (Aos Scéal Éireann) where you'll find seanchaithe such as Éamonn Ó Conghaile, Seosamh Ó Maolalaí, Máirín Mhic Lochlainn, Aideen McBride and there are references to various storytelling events held through the year - Cultra, Scéalt Shamnha, Cape Clear srl. There are also several interesting 'in memoriam' notices to well-known figures such as Cáit Bab Feiritéar (though apparently Ó Bhéal an Bhab is no longer available from Litríocht). Among the documents, there's this small anecdote I'd like to quote to you, taken from 'Dáithí Ó hÓgáin on Storytelling' -
'I come from County Limerick and there's a town there, Ballyneety (Baile an Fhaoitigh).
Whitestown, it means actually, and there was a beggarman passing through there one day (and you couldn't get more local than this, I suppose) and a dog ran out, a savage dog and he bent down to pick up a stone to keep the dog away from him, naturally. But the stone was stuck to the ground and so the dog went and tore the arse out of the poor man. And all he could say was - he made a little verse: 'Is olc an baile, Baile an Fhaoitigh, go bhfuil clocha ceangailte ann agus madraí scaoilte.'
There is one thing I've noticed however and that is (in the story I'm still working on - Féidlim Tonn Rí 's Castle) that there are certain phrases or parts of the story that keep coming back, that are repeated. Obviously this is a technique for memorising the story and it also becomes part of its structure, but I also wonder whether it isn't a kind of a chorus that everyone joins in.
