 Colonel Harland Sanders (qv), founder of Kentucky Fried Chicken,  appeared on the 1 December 1963 broadcast. However, the panel wasnt  blindfolded due to the fact that he wasnt well known at the time.  He later would appear on a 1970 broadcast of the syndicated version  of the show only this time he was now a full fledged mystery guest  and the panel was blindfolded on that occasion.
