New viewers begin here: even if you know nothing of the previous five series of Waterloo Road, you could start to enjoy the drama set in a failing comprehensive in Greater Manchester with the opener to series six, as the writers have rather winningly taken the precaution of barely mentioning anything that went on in previous years - not even the teen suicide pact that ended series five. And, as with many a failing school, some of last term’s teachers have departed (also unmentioned), including those played by Denise Welch and Angela Griffin, but back comes former Waterloo Road pupil Janeece (Chelsee Healey), now up the duff and, defying our belief, she's the new school secretary.

Comic Greg Davies has made us wait for his solo debut - he’s in his early forties, appeared at the Fringe as part of sketch group We Are Klang for a few years and more latterly has been starring in The Inbetweeners on Channel 4 as Mr Gilbert. Before that he was a drama teacher in a secondary school for 13 years. But boy, was it worth the wait.

He may call it Titting About, but Kevin Eldon’s show, his first as a solo performer (at the grand age of 49), should be made compulsory viewing for young comics. For this is a man who has learned his craft, the value of good writing, of stage presence, of timing and myriad other things while putting together a lengthy CV that includes Nighty Night, I’m Alan Partridge, Fist of Fun and Brass Eye. If you have seen him in any of those, you will know he's a comedic actor of great range and restraint.

This is a show of such originality and inventiveness that I will struggle to convey just how much fun it is to watch a man perform sight gags and physical comedy for an hour - and who does indeed appear throughout with a strip of black gaffer tape over his mouth.

Celia Pacquola made her Fringe debut last year after storming various comedy festivals in her native Australia with a show about her boyfriend’s infidelity and, while it was entertaining enough, it lacked a bit of oomph. But her new show packs a real emotional and comedic punch and displays a noticeable development of her writing and performing talents.

Doc Brown comes on stage in the hip-hop uniform of all-black clothing, lots of bling and black-out shades, and starts rapping “It’s all about me” in suitably bombastic tones. But Brown isn’t all he seems, as the rap peters out, the gear comes off and he is no longer a rapper, but a stand-up making his debut at this year’s Fringe. It's a terrific and captivating opening to an hour that speeds by.

Going to a late-night comedy show at the Fringe is always taking a risk, not least because every drunken fool in the place, with their oh-so-funny heckles, thinks they’re funnier than the performers. And so it proved at the performance I saw of this deliriously funny sketch comedy, performed by five fit young chaps, in which the payoff to one skit involves one of them going buck naked.

He may describe himself as “a Geordie chancer”, but in reality Jason Cook is a warm comic whose material is utterly devoid of cynicism. Yet he’s far from being pious - he spices up his act with caustic barbs for deserving targets (quite often himself) and has a raft of sharp putdowns for hecklers who think they’re wittier than he is.

"Welcome to the new-look, high-risk, high-speed show,” said presenter Chris Tarrant at the top of the programme. Well, sort of new-look; the opening titles are new (although they still haven't managed to put the question mark in the logo), but the music is the same and the set appears to have had no more than a dust down since the last series. But let’s not quibble, as producers Celador have indeed rung the changes and in doing so have given the long-running show a much needed fillip.

This award-winning series, created by Tom Kapinos in 2007, is groundbreaking television even by Showtime’s daring standards. Californication is a dark - very dark - comedy drama about Hank Moody (David Duchovny), a bad-boy writer who has lost his literary mojo, but absolutely not his mojo mojo, as it were; it has nudity a-gogo, frequent sex scenes, recreational drug-taking and frank discussion of sexual matters.
