Eddie Butler tells one of the most remarkable stories in the history of world sport. How it was that for over 80 years, the mining communities of the South Wales coalfield produced some of the finest boxers the world has ever seen - Jimmy Wilde, Tommy Farr, Howard Winstone to name but a few. He also examines how it was that when the coalfields flourished, the mines also contributed the backbone to Welsh international rugby squads that were truly world-beaters.
