I don't think anyone's saying Mitt's a liar, but things don't add up for a couple of reasons.
1. Why would Reg Grundy Productions keep the less-successful version of "Sale", which only ran for 20 months, yet not hold on to the first 5-1/2 years of the far more successful version, esp. when the daytime and syndie versions aired concurrently?
2. Why would RGP not keep the daytime version, yet keep "Scrabble" which aired on the same damn network for about the same amount of time?
BTW, because Mitt told you so is not going to fly as an answer.
Again, this doesn't mean Mitt is lying, but he's also going off a 20+ year-old memory, so he could easily have his facts off. But hey, if you want to take it all at face value and get defensive with us just because he's the one who worked on the show, while we're just trying to argue logic, be our guest. It only goes back to the advice you refuse to heed.
