The premise was simple, the characters were somewhat one dimensional, and the school children were quite clearly in their 20's, but that did not hinder the success enjoyed by Please, Sir!.

Never to be accused of being a complicated show, John Alderton starred as Bernard Hedges, a newly qualified teacher at a tough south London school. The plot centred on the unruly children in class 5C, a group of no hopers that would constantly test their young teacher.

The other half of the action occurred in the staff room where Bernard's colleagues used to regroup, along with Potter the caretaker, the real power holder of the school.

Please, Sir! is still fondly regarded as the best and most popular sitcom of its time.
