This is a segment from the last "CBS On The Air", in which Art Linkletter does a mini-tribute to game shows that aired on CBS and in the process appears on the
Match Game and
Price is Right sets. But the reason I posted this is because at 6:00 there's a clip montage of Bob hosting the nighttime show!
...Yes, I said
nighttime.
Okay, now for speculation as to date -
* This was filmed before Fall 1978, as the
Match Game set is the original.
* The Dice Game board is sitting near the Turntable for some reason. The "price" is $5,279, and I thought this meant it was from May 2, 1979 (
5/
2/
79) but the above detail confirms this isn't the case.
* Since the board is using "7" and "9" it might be before they changed the rule to force the numbers as only 1-6 (which happened by June 29, 1977).
So I would wager that this is from Spring/Summer 1977, shortly after Dennis James taped his last episode but after Bob taped a few nighttime shows (which proves that the opening "sparkles" present on #300N were introduced when Bob took over).
Finally, for the curious, the 5/2/79 show was #3273D
