Good luck for Boxing Day to Brian Clifford, who, as clerk of the course at Kempton, is in charge of proceedings next Wednesday for the track's festive showcase, the King George VI Chase. But don't be puzzled if you hear people calling him "Barney". His nickname dates back to when he was a jumps jockey and a horse in the stables where Clifford was based shared his christian name. No complaints from Clifford, though. At least the name chosen for him to avoid a mix-up between the two ensured that he avoided being gelded.
