It was arranged by John Robinson, a bandsman in Northern Ireland. I was told by the late William Douglas, who gave me the music parts, that it was arranged in memory of the Darkley killings (or Darkley massacre). This was a gun attack carried out by republican terrorist members of the Irish National Liberation Army (INLA) on worshippers attending a Mountain Lodge Pentecostal Church service on 20 November 1983 near the village of Darkley in County Armagh, Northern Ireland.
