I've found quite a few West Cork songs in the School's Collection whilst researching a book, Mizen: Rescued Folklore. I've yet to collect the melodies though. See list below.

Crookhaven
The Day Star - about a shipwreck in Crookhaven
The Hoche Expedition - about a shipwreck in Dunmanus Bay
The Wreck of Dunlough Bay - about the wrecking of a ship named the Memphis.
The Parish of Sweet Kilmoe - an emigre song
The Berehaven Regatta - about a regatta between the men of Crookhaven and Berehaven; still sung today
The Loss of the Lady Charlotte - another song about a shipwreck; there are numerous versions

Lissagriffin
The Bold Three Castles Head
The Hipped Old Horny Cow - written by a man named John Donovan from Mileen, Goleen
Dan Hurley's Daughter Han - another emigre song
Old Charlie - about an old but faithful horse
The Land of Canawee - another song about Charlie
Dhurode's Fair Hills and Valleys

There a loads more from other villages and townlands.
