This surprisingly standard-issue sitcom from the Green Wing team stars Sarah Alexander (Coupling) as Gemma Jones, divorced from Jason (Neil Morrissey) and juggling maternal duties with an attempt to kick-start her love life. It's the candidates jockeying for boyfriend position who provide the thrust of the action, with safe choice Tom (Nathaniel Parker) vying for pole position with toy boy Billy (Robert Sheehan).

This latest attempt by BBC One at a mainstream sitcom is a ditzy domestic affair about single mother Gemma Jones (Sarah Alexander), who spends her life dealing with her twin girls, her midlife-crisis-suffering ex (Neil Morrissey) and his stereotypical Swedish girlfriend. So when a handsome father (Nathaniel Parker) asks Gemma out on a date while she's on the school run, it's a welcome offer. That is, until her student son returns from a backpacking trip with his flirtatious friend Billy (Robert Sheehan) and Mrs Jones unexpectedly finds she's got more than one love interest. Solidly played by a strong cast, this comedy is gently amusing rather than laugh-out-loud funny.

Starring Sarah Alexander as Gemma, a divorced mum, and Neil Morrissey as her ex-husband, now shacked up with a stern eastern European woman, it may be too early to judge this new sitcom made by an all-female team of writers and producers. Yet the lack of a laugh track is ominously matched by a lack of laughs in this opener, with script and set pieces feeling contrived, as Gemma is caught between dating a leery dad from the school run and experiencing a frisson of desire for her son's best friend.

Before the arrival of his guests tonight, the affable Welsh comic warms up his audience with his usual display of sharp wit and natural charm. Apart from some mischievous exchanges with his studio audience, including a mock-earnest argument with several of its members, there is little that differentiates this show's format from rival entertainment programmes. But the amusing, fast-paced interplay between this evening's chosen guests - Ronan Keating, Jason Manford and Neil Morrissey - proves engaging. The incorporation of live music is a fail-safe formula, although whether Brydon's singing voice adds much magic to the blend is debatable.

The beauty of Rob Brydon as a chat show host is that without seemingly trying too hard or forcing the pace he manages to put a smile on your face. And boy, can he play a crowd. Even before his guests have arrived tonight, he picks a comedy argument with a woman in the audience who is in a wheelchair, and it comes across as sharp, good-natured - and very funny.

Then the revolving bookcase delivers Ronan Keating, Jason Manford and Neil Morrissey by turns, and once they're all on the leather sofa the chemistry works a treat. Plus, of course, everybody gets to sing.

Comedies have always been big on friendships, be they soulmates or odd couples. Men Behaving Badly's Gary and Tony were always the former and so it seems are actors Martin Clunes and Neil Morrissey: writer Simon Nye admits that it was sometimes difficult to see where his scripts ended and real-life began. There's a chance to witness some of that spark here thanks to a montage of very funny bloopers. Of course, get the chemistry right and you have a mucker for life - as the 295 episodes of Last of the Summer Wine demonstrate.
