 The original pilot was broadcast in 1973 as part of BBC1s  _"Seven of One" (1973)_ (qv), a series of potential pilots  showcasing Ronnie Barker (qv). (Seven Of One featured one other  pilot which was eventually made into a series; Porridge). When the  series was properly made and shown (in 1976), there were a few small  changes, including a different actress playing Nurse Gladys Emanuel  and a different location for the shop.
