Commentary
Notes
Nobby Leach, the Minister for Magic at the time of the Quidditch World Cup in 1966, denied having anything to do with England's Muggle football win at that summer's FIFA World Cup (QWC, Pm).
Royston Idlewind also shows up in later Quidditch history - off the pitch - at the Quidditch World Cup in 1974 (QWC).
