There's an irony about days like today. Hadn't it been for the influx of English people into Wales and the English media, things that could be described as the essence of Welshness, such as rugby, would never have happened. If Wales had grown organically in the 1800s, instead of what actually happened because of coal, it's almost certain that Wales would never have been interested in rugby, or singing for that matter.
Funny how things work out.
