The following is the text of a message that someone sent to Sonny Ochs. So, I don't know who wrote it...
MacColl wrote "Shoals of Herring" for the BBC radio documentary "Singing The Fishing" in the Radio Ballad series of the late 1950s. It's about the herring fisheries off the east coast of England and Scotland. It was quickly adopted into the oral tradition in Britain and Ireland. At some point, the English habit of dropping aitches met with Irish national pride, and someone must have recorded it under the title "Shoals of Erin". I don't know who it was, but it must have been someone whose recordings have had some lasting impact, as this controversy surfaces from time to time.
