As a comedy sitcom this had everything going for it, for a start it was written by Jimmy Perry (one half of the famous duo who wrote Dad's Army and Hi DE Hi), a super pair of leads with Peggy Mount (who could literally drag a comedy performance out of anyone in her air space) and the often hysterically funny Hugh Lloyd. So why is it not remembered today and faded away after only thirteen episodes? I think the problem lies with the first series and something that happened each week after the ATV zoom faded out. The title sequence featured Peggy and Hugh singing about their love for each other. Which might have been OK for the first episode or a special,but the same (what can be described as a) wailing dirge repeated week after week probably had many rushing for the channel change button? Shame really as those who turned over missed a good treat. In the second series the producers obviously realised the mistake and the theme tune sequence was replaced with a lively contemporary electronic number on the same lines as "George & Mildred" type theme tunes, but it came a bit too late perhaps in recovering viewers?
