Very happy: Merrick Watts, Sophie Monk and Jules Lund.

"We've never been happier," Jules Lund says repeatedly.

And today he's bringing the joy to listeners on 2Day FM, where - squeezed between the songs and promos and traffic reports and news updates and ads, for McDonald's and P&O and Ella Bache's "famous college of skin and beauty" - there are snippets of the radio station's new breakfast team.

Welcome to the All New Breakfast With The Stars, formerly known as Breakfast With The Stars.

"It is a new show. It is a new kind of feel, I suppose," co-host Merrick Watts says with conviction.

The Sydney radio station's old top-rating team of Kyle Sandilands and Jackie O, who have switched to Kiis FM, are a hard act to follow. The breakfast rivals have been boxing each other's ears for weeks. Kyle has called Merrick a "f---head". Merrick called Kyle "morbidly obese".

Sandilands, though, is probably not tossing and turning in his early-morning sweatpants after Monday's debut by 2Day's new team. It was a likeable if unremarkable start for Jules, Merrick and Sophie Monk, "with" Melanie Brown.

The show starts six minutes after 6am, broadcasting "in Sydney and across the world". Jules, Merrick and Sophie are in the studio. "With Mel B" is broadcasting from her bedroom in Los Angeles. It's breakfast radio, so no one needs surnames.

With so many voices competing for air time, they adopt roles to assist listeners. Jules: "Happy Chappy." Merrick: "Medium Rare." Sophie: "Ditzy With Disconcertingly Low Voice." Mel B: "With Accent."

Listening for three hours is like speed dating your second cousin - immediately familiar and mildly awkward. Long-time 2Day FM listener Zona rings to welcome them to "our family".

Sophie's first "scoopla" segment of the morning reveals Britney Spears went shopping, while John Travolta did not make any new year's resolutions. I repeat. Did not make any new year's resolutions.

Breakfast radio is built on amusing anecdotes and prize giveaways. Men play at being blokey blokes. Women are twits in heels. It's early days but there is little sign Jules & Co will stray far from the mould.

So we learn Merrick's brother has named his dog after their dead dad. And he has diarrhoea (Merrick, that is, not his brother or his dog).

Sophie has been to the gym. She is a vegetarian who once turned down a $1 million commercial for a burger chain. "Eat the meat, Sophie! Eat the meat!" screams a listener.

Sophie reveals which One Direction member she fancies. But I am too busy making breakfast for my young daughter to hear.

"We've never been happier," Jules says.

A question comes in for Mel B: which accent do you sing in? "Accents go out the window when you sing. It kinds of becomes generic-ish," she says.

The same is true of FM breakfast radio in Sydney. Padding out the ads and pop songs and promos are short stories about celebrities and social dilemmas, pets and poo.

Over on Triple M, Belle calls in to talk about the time her dad revealed he was gay. How was your mum, Belle? "Bloody devastated."

WSFM is playing Van Halen. Voice of Islam 87.6 is preaching: "Hellfire has been veiled with desires. Paradise has been surrounded by hardships."

On 2Day FM, an ad for Channel Seven raises a question of social etiquette: how many cheese courses can you serve at a dinner party before it gets weird?

"Every time that you get undressed, I hear symphonies in my head," sings Jason DeRulo. I feel the same whenever I hear Sibelius' Sixth.

Sando jumps in with a traffic report: a car has caught fire in Terrey Hills and is causing a distraction eastbound.

I'm distracted by these distractions. In a three-hour radio program there is relatively little time spent With The Stars. And it's a shame. Because they seem nice. Happy, certainly.

It's not clear to me if the stars are the hosts or the guests. I guess we all are. Even you.

The 2Day FM team have some fun in an interview with Geoffrey Rush. There's an agonising cross to former Saved By The Bell actor Mario Lopez at the Golden Globes.

"Always fun talking to you guys," he says, despite never having spoken to them before.

"We've never been happier," Jules says, again.

To their credit, 2Day FM's new team try for light and shade. There's a lengthy discussion about the death of Daniel Christie and the problem of street violence. It's not as awkward as it sounds, alongside a story about Justin Bieber throwing eggs at his neighbour's home.

"We've got to do something about Justin Bieber, and obviously all the coward punches," Jules says.

It's a challenge squeezing four hosts into a single studio (and an enormous bedroom in LA).

"We're still learning the rhythm of the group," Jules tells Fairfax Media after the show.

"This morning we were almost too generous with each other. As we get to know each other more, we will push each other around more."

The All New Breakfast With The Stars wraps up its first outing at 9am. But first the team give themselves a score out of 10. Jules rates them a 7.5. Sophie gives them a four. "I failed at school, so four is good," she says.

"We are having the time of our lives. In fact, we have never been happier," Jules says.

Until tomorrow morning, at least.
