Career
Playing at scrum-half in rugby union, he made his first-class début for Pontypool in 1981, but not long after broke his neck. Despite being told he would never play again, he was back playing for Pontypool within a year. He only gained one cap for Wales — against Australia during the 1984 Australia rugby union tour of Britain and Ireland which Wales lost 28–9.
Despite the loss Bishop was the only player to score a try against them.
Bishop had played understudy to fellow scrum-half Terry Holmes, and when Holmes switched codes to rugby league in 1985, many expected Bishop to finally be given his chance to play for Wales permanently. However, during a match versus Newbridge, Chris Jarman received a broken jaw in an off-the ball incident.
Jarman brought a private prosecution resulting in Bishop being given a suspended jail sentence and an eleven-month ban by the WRU. The Welsh selectors instead picked Robert Jones of Swansea Reconstruction Finance Corporation. Despite repeatedly putting in outstanding performances for Pontypool, Bishop was never picked for Wales again, though his case was not helped by several of Bishop"s antics off the field Finally in 1988 Bishop was lured to rugby league and he signed for Hull Kingston Rovers, and subsequently played for Salford, and London Crusaders.
Following rugby union turning professional in 1995 Bishop returned to Pontypool as player/coach.
Although Pontypool had been relegated from the top flight of rugby in Wales in 1995. Pontypool then played Cardiff in the next round of the cup, where they were heavily defeated, but Bishop faced his old adversary Robert Jones for the last time.
