Alison & Larry: Billericay to Barry
8pm, Gold
Here’s undemanding comfort TV, as old friends Alison Steadman and Larry Lamb retrace the frequent journey of their Gavin & Stacey characters and travel, by electric car, from Billericay to Barry. It’s slightly mundane and entirely charming – the pair reminisce about their careers, hang out with Russell Tovey and are commemorated by Basildon council. It’s narrated by Joanna “Stacey” Page, which gives the whole enterprise the feeling of an unofficial reunion. Phil Harrison

A new series of a show that doesn’t seem to deal in series, but rather in a perpetual repetition of a formula. It remains a very watchable formula, too – this latest run begins with a trip to Nottingham where DJ Janelle is basing her menu on her Caribbean heritage. Can her guests handle the heat? PH
