Walmington-On-Sea 333 has spotted that Parsley Sidings is currently on BBC 4extra. If you aren’t familiar with this series it is often considered a sequel to Dad’s Army.
Although penned by a different writer (Jim Eldridge) and having no direct connection to the characters or setting of Dad’s Army it had a similar period feel and gentle comedy style. Moreover the core cast included Arthur Lowe and Ian Lavender, playing a pompous stationmaster and his stupid-boy son. Sounds familiar?
