Personally, I found Alan Carr's recent statement that gay men make the best chatshow hosts because they are "gossipy" rather annoying - not only because it relies on a particular stereotype, but also because it would imply that Graham Norton is better in the field than Jonathan Ross. For all his faults, Wossy still has the edge on that score. That said, the last series of Carr's show was often hilarious with the right guests. Whether Noel Fielding and Mariah Carey fit into that category, we'll have to wait and see.

This week the pop quiz is the launch pad for the manic wit of regular team captains Noel Fielding and Phill Jupitus, guest host Alex James and panellists Peter Serafinowicz, Holly Walsh, Newton Faulkner and Jessica Origliasso. That means there's a range of comic styles as divergent as this show's musical tastes usually are from the current Top 40.

There's life after Simon Amstell for Buzzcocks

We go behind the scenes at the comedy music quiz, where it's all "flowers and unicorns" according to Noel Fielding.

The music panel show continues as Noel Fielding settles into his new role as permanent team captain opposite the immovable Phill Jupitus. Comedian Rhod Gilbert takes the guest presenter's chair tonight (replacing Simon Amstell who has now left the series). Fielding is joined by sports presenter Gabby Logan and Jeremy Reynolds from trendy electro band Hockey. Facing them is a far more intriguing line-up comprised of Spandau Ballet's Martin Kemp and gravel-voiced comedian Greg Davies, who plays the angry head of sixth form in The Inbetweeners.

The line-up seems to change as often as the cast of your average soap but somehow this comedy music panel game has endured. Since the show's inception in 1996, Mark Lamarr and Simon Amstell have had spells as presenter, and Sean Hughes and Bill Bailey have both taken the role of regular team captain. Only Phill Jupitus has lasted the distance. Even the tone of the show has changed over the years - particularly after Amstell took over presenting duties. He put his own quirky, irreverent and somewhat juvenile mark on the programme and when team captain Bailey quit last year he referred to the guests as "gormless indie twerps". Now Noel Fielding (of The Mighty Boosh fame) will take the captain's seat opposite Jupitus, and Amstell will be replaced by guest presenters (beginning tonight with Gavin & Stacey's James Corden). Whether the show will survive after such a flurry of changes remains to be seen. Although Buzzcocks has long since left the illusion of improvisation behind, it has certainly become much "trendier" in recent years and, thanks mostly to the wit of Amstell and Jupitus, it has remained entertaining. Now one must hope that Jupitus can carry on that tradition alone. Joining the teams this week are the potentially dull Tom Clarke of indie band The Enemy and singer Paloma Faith but fortunately actor/comedians Ben Miller and Janeane Garofalo should help keep the proceedings lively.

Simon Amstell made this pop-music panel game outrageously, unmissably funny - but he also made it his own. It was Amstell doing a comedy act, with a quiz interrupting on occasion. Now he's made the logical decision to concentrate on his own stand-up, where he won't have to weave his jokes around asking someone from GMTV questions about Climie Fisher. So Buzzcocks has been left to go down the guest-host route. First to try to follow Amstell is James Corden, co-creator of both the untouchable Gavin & Stacey and the relentlessly (and slightly unfairly) panned Horne & Corden. His appearances on panel shows so far have been more fun for him than for us, but he's naturally funny and he knows his music. Also new, but full-time, is team captain Noel Fielding of absurdist rock-star comedy duo Mighty Boosh. He should slot right in opposite Phill Jupitus, who's now in his 14th year of humming intros and picking has-beens out of line-ups.

Fans of the pop quiz will have been gutted by Simon Amstell's announcement he was quitting to concentrate on his live work. We hoped he was joking - but for once he was deadly serious.

On Amstell's watch Buzzcocks was unmissable weekly irreverence. He read an autocue like nobody's business but the best stuff came off the top of his head - scattering unpredictably like priceless comedy dandruff.

Guest hosts starting with James Corden will helm the new run - but generating that relaxed, free-wheeling chemistry that flourished under Amstell will be tough for anyone dropping in. Noel Fielding, who's been excellent value in the past, becomes a team captain opposite Phill Jupitus.

For those worried that they'd not seen much of James Corden on their screens recently, relax, he's back. He hosts the umpteenth return of Buzzcocks - along with Noel Fielding, who's back as a team captain. The quick-witted Simon Amstell is gone, so now it's a revolving-door host policy, with the ability to read an autocue and laugh generously at unfunny gags by Phill Jupitus the only qualifications that seem to be required. Fine, anything that keeps Mark Lamarr from clawing his way back on to our screens.

Pop World has never been the same since Simon Amstell left. Will Buzzcocks go the same way, particularly now it's going down the rudderless route of guest hosts? In fashioning himself into a TV personality, tonight's host, James Corden, hasn't been quite as funny as he thinks he is. Still, he made a good fist of things as a guest captain last year, and he's not the only newbie trying to impress here: achingly hip Noel Fielding is now a permanent fixture.

This series of the madcap quiz show may not have struck the same irreverent chords as it did in its Nineties heyday, but it's been entertaining all the same. Concluding the current run, this episode sees The Mighty Boosh's Noel Fielding, DJ Tony Blackburn and presenter Zoe Salmon join team captains Jack Dee and Ulrika Jonsson and regular guest Angelos Epithemiou - the curmudgeonly alter-ego of comedian Dan Skinner - for more surreal tomfoolery.
