If you're up late tonight — or setting your TiVo or VCR — take note of what's on Game Show Network's Black-and-White Overnight block. The episode of To Tell the Truth scheduled is one that has a then-unknown Cicely Tyson as one of the impostors. And the episode of I've Got A Secret is supposed to be the infamous Tony Curtis episode that caused the firing of the game show's producer-creator, Allan Sherman. Details on the latter can be found in a posting I wrote the last time this one aired.
