I first heard "Fiddler's Green" sung by a certain Joan Collins on Wally Whyton's Folk Music programme sometime in 1983. I immediately transcribed it and very much enjoy singing it, as do no doubt the entire population of Ireland where it is popularly believed to be a traditional Irish song. This is not the case, however as Roy Palmer in his masterpiece The Oxford Book of Sea Songs
says that the song was written by John Conolly in 1966.
Even though the song is a fisherman's song I find the line ".... and I'll play me old squeezebox as we sail along, ..."
very apt in keeping my naval background, love of the sea and much battered concertina.
