Hi Conrad , when I was a child in Dipton Co Durham I grew up listning to the Tommy Armstrong songs, My father and uncle used to know Tommy very well, in fact as Tommy did not sing so good and my uncle was a good singer they would tour the local pubs of Dipton, Tantoby and Stanley together, my uncle singing the songs Tommy wrote for a reward of a couple of pints Tommy did not write tunes but just wrote his songs to tunes which were popular at the time. For The Durham Strike, as Tommy called the song known as Durham Lockout the tune he used was "Castles in the Air ( also known as Ball of Kerrimuir). However when The High Level Ranters recorded the album "Tommy Armstrong of Tyneside" Tommy Gilfellon sang the song to the tune of Come all ye tramps and hawkers. I was wondering which tune you were using on the abc file. Cheers Bill
