| In my collection I had a Shep program tentatively marked "1971 Stamps".
I am fairly certain the actual air date was 040271 because early in the program, Shep states "it is Friday", and later he has a commercial for Palisades Park, and sez "it opens this weekend".
According to Wikipedia, the park opened the weekend before Easter, (which fell on the 11th that year.)
Sadly, the park closed that year for good, in September....
