Martin,
I heard the date reference on a trad programme on RTE but I cannot remeber which one. I was on my way to or from Ennistymon the year Frank gave his wonderful lecture and he sang this at the beginning.
The way he roars Cockles and Mussels definitely makes you see her shouting from behind the barrow. Her morrels are of no concern to me. I love her.
Yes I think this is the song Frank was referring to.
