This article came about after a colleague asked what music I was listening to. When I told him it was Gil Scott-Heron he informed me that the musician’s father played for Celtic. I found this an interesting piece of trivia but when I thought more about it made me want to delve deeper. If Gil Scott-Heron was performing in the 1970s his father must have played for Celtic long before then? In the early post war era, there can’t have been many black footballers in Britain? How did a man from North America end up playing football in Glasgow?
