(Please accept my apologies for the first one accidentally dated incorrectly.) Evidence for submission #190523-024049-022000 and #190523-025237-872000 is in the form of TV listings. The combination of celebrities listed for this Celebrity Bowling episode is actually a combination found on Celebrity Tennis. The chances of the same combination of celebrities being put together for both Celebrity Bowling and Celebrity Tennis is astronomically slim. The episode can be found on many dates, but the earliest one I can find is May 19, 1974. This is from the San Francisco Examiner May 19, 1974: I was going to give you more listings, but the files will not upload. I get an "internal server error." Hopefully, this is sufficient. I would also say that all four of these celebrities were active on the celebrity tournament circuit, so it makes a lot of sense that Celebrity Tennis would be their game. Thank you.
