How many herring songs can there be, he asks. About as many as herring fishermen, I'd guess. Putting "herring" in the search box above right got me 25 hits, not all of them about herring, but all of them mentioning herring. Notably there is Ewan MacColl's Shoals of Herring and Gordon Bok's Herring Croon. How about it, Vic, are any of these the right ones?
