Writer Vince Powell used the same plot-line in an episode of 'Mind Your Language'. The comedy is derived from the fact that a character who was left on an orphanage doorstep as a baby is shocked that his biological parents are not as well-bred as he is. Aside from the audience being asked to swallow a huge coincidence that he would be left on the same doorstep on the exact same night, the big 'twist' (that the baby left by the two 'parents' is the other gender) can only be kept under wraps (pardon the pun) by referring to the left baby as 'it' or 'your baby','my baby' etc so it sounds unnatural and somewhat telegraphed (even though I already knew the outcome from having seen it done in 'Mind Your Language'). Naturally, if they had said 'her' then the story is over.
In the 'Mind Your Language' episode, there is a cool scene where the character imagines what he would be like if he had grown up with the people who he believes are his biological parents. It might have been funny to see Donald Sinden ham it up in a similar scene but that wasn't done here.
The episode is notable for casting 2 actors from 2 different ITV sitcoms that were very popular in the early 70s: Doris Hare from 'On The Buses' and David Barry from 'Please, Sir'. Also of note is that the actor who Donald Sinden's character thought was his father was in reality only about 7 years older than him. One last noteworthy thing is that there is less animosity than usual between the two main characters.
