“Crooked Jack” The song is based on the accounts of appalling working conditions for Irish and Scottish workers on a hydro dam project as well as of their experience of working more broadly. ‘The Ganger” was the foreman of a group of working men. Dominic Behan wrote the song about the men who came from all over Britain and Ireland to work in the Scottish Highlands to build the Hydro-Electric dams. The workers were promised good money and outdoor work surrounded by stunning scenery, the reality saw them working in dangerous and poor conditions.
