Slightly off-topic, but when $10,000 Pyramid briefly moved to Los Angeles in November 1973 for three weeks, they brought the entire set over, unlike Password.
I never got why they moved to L.A. I heard one account say that it was due to CBS Game Shows doing special celebrity themed weeks (would be interesting if TJW and Gambit actually had them), another that Bob Stewart wanted to try something different, and another that it was per CBS custom at the time with celebrity game shows. Which is it?
