Hi Leadbelly,
You must be listening to The Ludlow Trio,a Folk Group from the 60s. When the record was made in 1966, Jim McCann was in the group, along with Margaret O' Brien and Sean Loughran .Their recording of "The Sea Around Us" by Dominic Behan became the first Folk record to get to number one in the Irish charts. It is interesting to note that the Dubliners, which Jim McCann later joined at some time, also released the song as a single at the same time, but the clean-shaven image of the Folk Group aws what people wanted at the time. It took a long time for our Beardy Bousies to get into the charts.
