I loved that show also!If i recall correctly it was on very late sat night and i had to sneak up late to watch it.
Did you get that show outside of Nebraska? For us, Creature Feature was a local show out of Omaha, NE with the host being Dr. San Guinary (John Jones - a local Omaha celebrity). It may have been a national feed from CBS (or NBC/ABC) - cannot recall which channel was which. They may have aired national feeds with local hosts. It was aired on Saturday nights here too.
I loved it! Great memories!
