Towards the end of a ridiculously easy and enjoyable hour spent in their company, Flap!’s singer and ukulele player Jess Guille described “Rock in Space” as “jazz-folk-disco” – and, you know, it kind of was. A bawdy, slap-happy five-piece from Melbourne, their root note is pre-war American jazz, but to that foundation they add ska, gypsy music, blues, folk and flickers of more contemporary styles, mixing them all together with deceptive ease. And although their defining aim is to get the audience to laugh, dance (and drink), they can really play, too.

Rosie Wilby: How (Not) to Make it in Britpop, Bongo Club ***

In the 1990s Rosie Wilby was lurking on the outer edges of Britpop with her band Wilby, whose giddy career highlights included opening for Tony Hadley (he evacuated the entire room for the soundcheck), being clamped outside the venue while supporting Bob Geldof, and getting their own plastic name tag in the racks of Virgin Megastore.

The purple cow has taken up its summer residency on the South Bank in London before making the journey to the Edinburgh Fringe in August. As ever, the line-up of performers is extensive: last night comic Tom Allen performed his chat show with the help of a few comedy guests.

It's always a pleasure to watch comics first seen and enjoyed playing a tiny room at the Edinburgh Fringe make their television debut; it's an even greater pleasure to see two immensely talented comics make such an accomplished entrée as Seb Cardinal and Dustin Demri-Burns did last night. But then they have a track record: in 2006 the duo (then performing as a threesome with Sophie Black as Fat Tongue) were nominated for best newcomer in the Edinburgh Comedy Awards.

Ricky Gervais doesn't make it easy for critics or viewers. He has always pushed the boundaries of modern comedy with a cast of unlikeable characters, starting with his 11 O'Clock Show inquisitor to deluded fool David Brent in The Office and failed actor Andy Millman in Extras, as well as “himself” in The Ricky Gervais Show and Life's Too Short. But within all his creations there has been an element of vulnerability that made them believable and ultimately sympathetic.

Storytelling, they say, is an almost lost art. Well, not while Benet Brandreth is around, it's not. Brandreth, Sandhurst graduate and a lawyer by day, studied Philosophy at Cambridge and has packed rather a lot into his life, real or imagined. He weaves a fantastical tale charting his story from graduation to last year - when, not for the first time, he saved the life of a member of the royal family.

In Seven Years in the Bathroom, which he premiered at last year's Edinburgh Fringe, Alex Horne attempts to shoehorn the average man's 79-year lifespan - in which he says a remarkable seven years is spent in the bathroom - into an hour's comedy. It's certainly high-concept, and there's an awful lot of comedy to be mined from the subject.

Lorna Watson and Ingrid Oliver, purely by dint of being female, have a burden of expectation before they even open their mouths, as the ghosts of French and Saunders stalk the corridors of the BBC. It's horribly unfair to saddle the newcomers with that burden of course, but, given the dearth of female comics on television, it's perhaps inevitable. Yet the fact that the corporation thinks highly enough of Watson and Oliver to launch them straight on to BBC Two, rather than the safer comedy testing ground of BBC Three, makes a big statement in itself.
