I have corrected what I think is a mkistake in the original version which talked about the emergence of "professional rugby union" in England in the 1920s. i am pretty sure this is wrong and the author was thinking of professional Rugby League, I have just changed it to rugby so that it is right even if a bit less informative than it could be. There was a big drift away from Wales to English clubs between the wars but the payments, if there were any, were secret.
