Guest star Sandy Barron (who played Grandpa's brother "Yorga" in several MT episodes) later played the role of "Grandpa" for made-for-TV Christmas special "The Munsters Scary Little Christmas" (1997) following the death of Howard Morton who had played the role since being cast in the 1987 pilot "Still Munsters After All These Years".
The first and thus far only version of "The Munsters" to feature lyrics with the memorable theme song. The lyrics are as follows; "We're the Munsters. We're the Munsters. We went to sleep many years ago, and we woke up with a brand new show. We're the Munsters. We're the Munsters... Today."
John Schuck who plays Herman Munster had previously played the role of Frankenstein's Monster in the 1979 TV movie "The HalloweenThat Almost Wasn't", as had his predecessor Fred Gwynne in the original series of "The Munsters" his previous credit being for a TV commercial.
