Yes, I am sure the referee is well known to many senior RTR members; first two initials BJ and was always known as John because of his most unusual first name !. Sorry, but I cannot help with the identity of the linesman.
Yes, the name of the ref is given in the 10 minute film of the game, available to watch via Google. However the name of the linesman is not and I too cannot put a name to the face. The incident leading to the sending off of Styles took place right at the end of the game, and following another incident, BJ called the game to an end with unseemly haste, leading to the commentator talking of a 'shambles', which was perhaps an understatement!
