That might explain why the CBS version added "The New" to its title a couple months into the run. A few times, it's been mentioned that viewers were confusing it with the Cullen version, and I could never understand why, give the CBS version had a new set and theme song. But if stations still aired reruns, it makes much more sense.
I wonder if that's part of the reason why "The Newlywed Game" added "New" to the title when it came back in 1985?
