Snuffy,
I sing the "Scotch Brigade" I learnt it first hand from George Belton, a farmer from Sussex. This was at the National Folk Festival in Keele quite a few years ago now. It's a great song. He also gave me a few more, one was a version of "Barbara Allen." (There was a thread on that song some time ago), and another called "The Streets of Rochester" (I think that was the title?).
I remember sitting in George's room armed with a tape recorder and sittng alongside me was none other than June Tabor. She asked me for a copy of The Streets of Rochester. I duly obliged and she sang it at a festival a few years later crediting George Belton and mentioning my name as well!!
