The Tommy Armstrong booklet was sold at South Shields Folk Club when it was at The Beacon prior to moving to the Marsden Inn. John Price was selling them at the interval and I suspect had been brought in from Birtley Club. I still have mine and it was a "shilling" (bought in Feb 1964) and like Jim did not know the tune of Trimdon Grange Explosion. A few years later heard Percy Webb singing "Go and Leave Me if You Wish It" (still have the recording) and Jim's version on his CD is to that, (the recommended),tune by Tommy Armstrong.
