Rob Brydon

Three into one can go, but they won't replace Humph

It is a tribute to the magnificent Humphrey Lyttelton that his replacement as host of I'm Sorry I Haven't a Clue has been named as Stephen Fry. And Rob Brydon. And Jack Dee. A revolving comic trinity, in place of the one god.

Fry, Dee and Brydon take on Clue

Stephen Fry, Jack Dee and Rob Brydon are to share hosting duties for a new series of BBC Radio 4 comedy panel show I'm Sorry I Haven't a Clue this summer. The series, which begins recording in April, will be aired in June and will be the show's first appearance since host Humphrey Lyttelton died in 2008.

The problem with Gavin and Stacey - other than James Corden's penchant for making a prat of himself at awards ceremonies - is not that it's terrible. It isn't. It's overrated but it can actually be rather sweet, albeit with self-consciously saucy bits (An old lady talking about drugs! How risque!) and an irksome jarring inauthenticity. Still, like the mint Baileys that so beguiles Bryn (Rob Brydon), Corden and Ruth Jones's comedy is something of an acquired taste and one acquired by rather a lot of people.

David Mitchell is fast becoming king of the panel game. He's scarily good at them, so it's no wonder he's called on to lend his wits to shows from QI to Mock the Week, and from Have I Got News for You to a Radio 4 show called The Unbelievable Truth that's not a million miles from this.

This is the one where he and Lee Mack are team captains and Angus Deayton is chairman. The contestants have to bluff their way through various tales while their opponents work out which are true. So, for instance, did Gabby Logan really once steal red liquorice from Madonna's dressing room? Under close questioning from Rob Brydon it looks less and less likely. And is the mystery guest really Logan's former gymnastics rival, Mack's swimming teacher or, in fact, Robert Webb's ex-girlfriend?

Brydon and Mitchell make a great pair and what could be a stilted format is saved by some brilliant interplay and Brydon's flights of fancy.

The idea of two people meeting, falling in love and getting married isn't a theme we don't know inside out but this works thanks to wonderful writing and a cast of highly talented people who seem to fit perfectly in their roles. Rob Brydon's Bryn is wonderful and his love of James Blunt (the one about the wise man by the sea) really made me laugh.

Gavin & Stacey is completely believable and the writing is razor sharp. British comedy has taken a bit of a dip lately with the sketch show taking over but Gavin & Stacey proves the sitcom is alive and thriving.

Talking of new shows, Rob Brydon is the jaundiced host of Annually Retentive (BBC3), a cheap and none too cheerful panel game. It pulls the rug from under all panel games.

I've been watching the first episode of Rob Brydon's new BBC3 endeavour Annually Retentive, which is now available on broadband. And, well, it's pretty good. [...] But the really brilliant thing, as with all Brydon's projects, is in his eye for the detail. The actual panel game itself is an excruciating fascimile of the real thing, complete with all the lazy tics and riffs.

Armed with a new director in Matt Livesy and script editor in Rob Brydon, Lucas and Walliams continue the high standard they set in the first season.

The Corbetts were on The Keith Barret Show (BBC2). The statuesque Mrs Corbett, it turned out, was the Crazy Gang's leading lady. One regarded her with little less than awe.

The Keith Barret Show (BBC 2) will probe the secrets of successful marriage, a subject on which Keith himself is sublimely at sea.
