Bob Bauld is an English actor whose career includes roles in British TV on "The Benny Hill Show" and "Doctor Who." It is likely he played one of the British football (soccer) players in the Match of the Week sketch on March 13, 1974.
It is possible, but unconfirmed that this Bob Bauld might refer to Robert Bauld, a Scottish professional footballer who played as a left half and inside forward in the Scottish Football League for Raith Rovers and Dundee United and in the English Football League for Bradford City and Chesterfield between 1920 and 1936. Born on March 14, 1902 in Cowdenbeath, Scotland, he would not have been one of the players but rather a spectator in some capacity. He passed away on October 19, 1980.
