TV preview: Till Death Us Do Part, BBC4

Are you ready for a cross between Festen and Mrs Brown's Boys? This is the weirdest contribution to the Landmark Sitcom Season yet. BBC4 has recreated a lost episode of the 1960s Alf Garnett sitcom Till Death Us Do Part using Johnny Speight's surviving script. And as they say on the internet, when you watch it your jaw will hit the floor.

Preview: Till Death Us Do Part

Unfortunately, this outdated set-up works against the production, reminding audiences how much our day to day lives have changed in 40 years - and not just with the advent of mobile phones and, dare we say it, Just Eat and Deliveroo.

While some comedians are lionised after they've stopped appearing on TV, others are quietly forgotten. Nicholas Parsons spends more than Just a Minute with Paul Merton recalling his partnership with one of the latter - Arthur Haynes. Viewers of a certain age will recall the partnership that pulled huge audiences to ITV in the 1950s and 60s. It's the comedy of a simpler, slower age; Parsons remembers how depicting a vicar in a sketch was considered disrespectful. There's nostalgia and curiosity value, not least with a priceless archive interview with writer Johnny Speight. Plus, rewarding glimpses of Wendy Richard, Patricia Hayes, Michael Caine and the Rolling Stones.

Written by Alf Garnett creator Johnny Speight, ITV's notorious, short-lived 1969 sitcom centred around the workers of a factory named Lillicrap Ltd. It starred a blacked-up Spike Milligan as an Asian immigrant named Kevin O'Grady (his workmates dubbed him 'P*ki P*ddy'). Speight maintains that he was challenging racism, but some felt the programme reinforced it.
