Concentration (NBC, Syndication)

This video collage that I made is from the well-known game show, "Concentration" that aired on NBC from August 25, 1958 to March 23, 1973. The hosts were: Jack Barry (1958). Hugh Downs (1958 to 1969) Ed McMahon (1969, very briefly) Bob Clayton (1969 to 1973) The syndicated version ran from September 10, 1973 to September 8, 1978. The host was Jack Narz. The theme song is from the 1973-78 Syndicated version. Supposedly, the theme song is called "Concentration Opening" by Ed Kalehoff. The NBC version fully exist (Big thank you to Secondchance1977 and the confirmation from Steve Beverly's Game Show Convention Center website). Some episodes were said to be found at the Library of Congress. Only a few remain on the trading block; Shokus Video is known to have a tournament episode from the late 1960s, and 12 Downs/Clayton episodes and a syndicated Narz episode have been found in the UCLA Film and Television Archive. The Museum of Television and Radio has in its possession one 1958 Hugh Downs episode, two 1971-72 Bob Clayton episodes and one syndicated Narz episode from 1974. The Narz syndicated episodes also exist. At least one Narz episode has been found on the trading circuit, from the final season in 1978 with the Double Play bonus round pick-a-prize package board. A ten minute clip of the end of an episode from 1974 also exists, in poor quality.
