There could possibly be some things on You Tube, but I'd think it would be extremely rare because of the combination of because of home VCRs not existing yet and the practice by the networks at that time of recording over tapes or destroying them. And there's also the problem of even if some copies exist somehow of the people who may have copies sitting on them and not allowing them to be seen, or not even knowing they exist and being in storage somewhere that hasn't been touched in decades, or has deteriorated to a point of not being usable any more, or in a format that equipment isn't available to play it.
