1980's Saturday Morning Historical Preservation Society

In 1981 at 11:30 in the morning on ABC, you would see Heathcliff ANd Marmaduke (along with a very catchy theme song). Officially considered to be the second season of the 1980 Heathcliff and Dingbat Show only with Marmaduke instead of Dingbat (obviously), they made 25 episodes of this version ( as opposed to just 13 "Dingbat" episode) which is why you probably remember the Marmaduke titles better than the Dingbat ones, if you remember them at all. Also note that this is a Ruby-Spears joint, NOT the DiC "Heathcliff and The Catilac Cats" version that was syndicated a few years later.
