If you want old comedy with a modern twist... ARE YOU BEING SERVED?/PORRIDGE

Sunday, 9pm/9.30pm, BBC1

To mark the 60th anniversary of Hancock’s Half Hour, the BBC has revived four golden oldies. First is a visit to Grace Bros, followed by fresh Porridge, with Kevin Bishop (right) as the grandson of Fletch (who was played by Ronnie Barker, inset).
