So we have one person with the experience and a different person who was the song writer.
Another good example would be Generations of Change by the late Matt Armour. He was neither ploughman nor fisherman nor did he work on an oil rig but in that song he wrote knowledgably about each of them incorporating the results of his research skilfully into his composition.
A mark of his success with this song is that it has been taken up by one of the last generation of bothy workers, Joe Aitken. You can hear Joe's very fine rendition by clicking here.
