Implicit in this, is, of course, the notion that The Folk were cherished for being too impoverished to afford means of written communication AND entirely lacking in the education that would make them literate. However, one often encounters the testimony of Traditional Singers saying they got such-and-such a song when it was written down for them. Indeed, Jimmy Knights says he got Out With my Gun from a written source, and his 1975 rendering of same (VOTP 18) is little different from the Manchester boadside of 100 years earlier. On the same volume you'll hear Willie Scott singing the Kielder Hunt which was written by James Armstrong in the 19th century.
