As astounding success for ITV on its original transmission (and fondly remembered to this day), Please, Sir! featured John Alderton (Upstairs Downstairs) as Bernard Hedges, a newly qualified teacher thrown in at the deep end when he is assigned to sort out the unruly class 5C at Fenn Street Secondary Modern School. Ably helped (and sometimes hindered) by his fellow teachers Doris Ewell (Joan Sanderson â?" Fawlty Towers) and Mr. Price (Richard Davies), he has to combat the wiles of school caretaker Norman Potter (Deryck Guyler) and the full might of Class 5C!
