Sorry about this folks, but I think I'm having a senior moment. I was about to retort that the song was collected from Lucy Stewart of Fetterangus in Aberdeenshire, and that it belongs in the public domain, rather than being the property of Nic Jones.

However, I've just searched my own extremely comprehensive database and can't trace a record of her singing it. Also, while Steve Roud's Folksong Index lists eight printed sources, it does not list a single sound recording of Mrs Stewart or anyone else singing The Plooman Laddies.

So, did Lucy Stewart sing it? If so, was her performance ever published? Or should I just go and lie down for 1/2 an hour?
