On \"Game Show Moments Gone Bananas\" (repeated tonight on GSN), there was a clip from an unidentified game show. The excerpt involved identifying the letter that could be placed in front of each partial word to form another word. Revealed one at a time, the clues were:
ART
ALL
ABLE
ARZAN
Nobody guessed T (or anything else) until \"ARZAN\" was revealed.
What show was this? Judging from the graphic design, it must have been from the 1970s or early in the 1980s?
