I was 6 1/2 when this show came on and almost 8 1/2 when it went off. I had the opportunity recently on Sell.com to buy a DVD set someone made at home from what it looks like to be VHS recorded directly from TV. Some of the episodes are really clear, some quite grainy but nevertheless so enjoyable. He had 51 of the 58 episodes recorded and charged me a very reasonable price. I have found two other shows that did not make it to DVD as well. I must have only watched this show when it was actually airing as I do not recall any of the episodes, only the characters and other regulars. Probably watched the second season on Saturday night. I don't recall watching TV in the evening during the week. That was homework time.
This show was, by far, my favorite family show with some real-life issues and arguments, flooded basements, parents quarreling, sneaky kids, etc. Patricia Crowley was my dream Mom; pretty, beautiful voice and way more patient and understanding than my own Mom and a little less OCD than my Mom. Dad was great and so were the kids. Not bad acting for young kids all just a little older than me now. BTW, oldest show on TV with the starring cast all still alive and well. Loved all the 60's character actors that guest starred on this show and many other shows. And it took place in Westchester County, NY, not far from North Jersey where I grew up. I am so elated to watch this show now around 50 years later. It really brought me back to my childhood.
Working on Nanny and the Professor (1970-71), 53 episodes that never made it to DVD although it is on in the morning on one of the classic TV stations.
