Searching for recording March 1978

[Phoenix]

Hello, everyone. I am searching for a recording from 1978 (possibly March). My grandfather was on the show and I would love to get a copy of it. His name is Robert (or Bob). Tall guy, short hair and glasses. I have always heard that he spun the wheel too hard and Bob made a funny comment about that.

Any information if appreciated!

Do you know what pricing game he played? This would certainly help folks narrow down the search.
