It wasn't until I still watched what will probably be the last (for the forseeable future) TVLAND DEATH... for all previous series there.... 3:30 am ONLY slot for MR Ed.. and realized how EARLY in the series "Pretty Little Filly" was, YEARS before Larry Keatings demise. (Maybe even still first season.)

I agree for the later (to fill in the season and still keep Kay around Jack Albertrson episodes... they were't that great.... but Pretty Little Filly is a real Classic.... one more on my DVR to be dubbed off to SVHS permanent collection somehow skipped the first time.
