I have Harry Gordon's autograph on my late grandfather's membership programme of events for The Glasgow Ploughman's Association; Harry was performing at one of their evening entertainments.
(My grandfather had left the farm to join the Glasgow police.)
One of the rules of the club was that they could not enter a ploughing competition until they had been 'ten years away from the farm' (so they had no unfair advantage?)
I remember being taken to some Stirlingshire ploughing matches in the early '50s, seeing my grandfather ad his friends carefully watching how each competitor steered his pair of horse, guided the plough, how straight the lines were - then picking up clods from the ploughed bit to see how well the earth held together.
