There is a story in Ireland of fishermen out at Sea and them hearing a strange and beautiful song vibrating up through their boat coming from the Sea.On returning to shore one of them wrote a piece of music based on the song they has heard.
Port Na Bpucai (Song of The Pooka).
Pooka being a Spirt, Faery of the Sea.
