Haven't heard the sea album you mention but I would guess Michael's song is 'The Leon' aka 'The Quilty Fishermen'.
Don't think we included Michael's version on the website but there's another version by a singer who lived not too far from Michael -Stevie O'Halloran - interesting locally made piece about a rescue from a shipwreck by local fishermen in CURRACHS (canvas canoes).
Michael used to make currachs - he has a fine one up-ended in his garden,
