Jonathan Ross

The quasi-anarchic chat show switches channels from BBC2 to BBC1. Which to me seems less of a jarring move than moving Norton's antics to a Monday night, when they'd seem far more suitable nearer the end of the week - although I suppose that would then create a clash with Jonathan Ross.

Although Graham Norton was in his finest form about five years ago on Channel 4, his squawky chat show moves tonight to BBC One. The first guests are that rare combination of the incomprehensible and the ageless, Ozzy and Sharon Osbourne, chat show perennial Ricky Gervais (who was on Jonathan Ross's show just a month ago) and ballad mistress Olivia Newton-John.

Barbra Streisand hasn't done a chat show in the UK since being lightly grilled by Des O'Connor way back in the 1980s. The reason isn't that she has something to hide, it's more that she really doesn't need to. She's such a preposterously massive star that Ross might just drop his tiresome "pretending all the female guests fancy me" routine and actually ask her some decent questions. We can but hope.

The once-disgraced television and radio broadcaster presents a show devoted to an interview with one of the world's best-loved stars, Barbra Streisand. Ross's at times brash interviewing style is not everyone's cup of tea, so it's a wonder that a star of Streisand's status would choose him for an exclusive chat. In her first UK studio interview since the Eighties, the A Star Is Born actress discusses her five-decade-long stage, television and film career and performs some of her classic hits as well as songs from her new album, Love Is the Answer.

Graham Norton on his move to BBC One: interview

As his chat show moves to BBC One, Graham Norton talks to Ajesh Patalay about money - and Jonathan Ross.

Why are so many of Ross's guests on his agents books?

Jonathan Ross has been accused of "stuffing" his BBC chat show with comedians from the books of his own agent, Addison Cresswell.

It's perhaps a little melodramatic to say that it's do or die time for Jonathan. But something has to give. His last series tailed off following the Sachsgate balls - not that he lost his wit, A-listers or even his cheek. But he'd lost a definite spark. And where his presence had been a comfort on a cold Friday night in, it became something too easily missed. His radio show is nowhere near as fun pre-recorded. And so he has to try something. Could he go on the offensive? No, he'd be slaughtered. So what? Let his guests speak? Seems unlikely. He's stuck. Writing this, we've become convinced, we're watching the death of this chat show. Shame.

Jason Byrne has the honour of providing half of the official comedy on 2 at the moment - Vic Reeves's panel show Does the Team Think? makes up the other 50% - though regular presenters Mark Radcliffe, Jonathan Ross and Alan Carr can all make you splutter into your cuppa. Byrne, though, is different: his show is proper stand-up, complete with audience interaction. There are a couple of silly sketches but the bulk of his half-hour is like being in a decent comedy club with a much-more-than-decent comedian. The lines are sharp but it's the atmosphere and delivery that make the show. This week's topic was food. Byrne asked if anyone had ever eaten something they shouldn't. "A tick!" came the bizarre answer. "You mean the insect?" asked Byrne. "Or maybe you stopped talking and meant to say 'tac' after that." Ace.

Chat will eat itself

So last night, Jonathan Ross, presenter of chat show Friday Night with Jonathan Ross, was a guest on the chat show Alan Carr: Chatty Man...

Are chat shows just a big joke?

Lucky America. Soon, more than 64 million US households will be able to watch Friday Night with Jonathan Ross - retitled The Jonathan Ross Show - on BBC America. For Ross this must represent the ultimate triumph.
