For many years, on the basis of Ewan MacColl's recording, I believed that in "The Wark o' the Weavers" the line "There's folk that's independent o' ither tradesmen's wark" was "There's folk that's independent -- a' ither trades must wark". I thought it was delightful irony: being (financially) independent was a trade like all the others, except for one detail.
