My Old Man is a sitcom starring Clive Dunn as retired and embittered engine driver Sam Cobbett.
Set in London, Sam Cobbett is the last tenant to leave an old house on a council-condemned road.
He goes to live with his daughter, her posh husband (Arthur), and their young teenage son (Ron), in a flat nearby.
The pilot starred Ronnie Barker as Sam Cobbett, with Graham Armitage and Ann Beach as Arthur and Doris, and was produced by Sydney Lotterby and Harold Snoad.
When the BBC failed to develop Gerald Frow's script into a series, Yorkshire Television stepped in, took over and introduced an entirely new cast with Clive Dunn in the lead part, whilst Ronnie Barker focused on his successful roles in Porridge and Open All Hours on the BBC.
