New Radio 1 breakfast DJ Nick Grimshaw played a radio edit of a famously foul-mouthed Jay-Z and Kanye West track as the first song on his show.

The 28-year-old, who replaced Chris Moyles, welcomed listeners to a “a brand new breakfast show”. He said he would last in the job “just until the country uprises and I get thrown back to the night-time”.

Grimshaw said he was “nervous and excited” but “desperate to get on with it” and kicked off his first show by playing Paris by Jay-Z and Kanye West. He joked that if he had played the full version it would have been “the world’s shortest stint on the Radio 1 breakfast show - three and a half minutes”.

Grimshaw, who admits he struggles with early mornings, said he set two alarms to make sure he got up.

He presented the programme on his own after station boss Ben Cooper said he wanted to move on from the “zoo” format of Moyles’s show in which his production team played a large part, and is expected to double the amount of music.

Grimshaw, known for his posse of celebrity friends including Lily Allen, Alexa Chung, Miquita Oliver and Harry Styles from One Direction, was a surprise choice to many, with drivetime show host Greg James expected to be the next breakfast host.

The presenter, known to fans as “Grimmy”, was brought up in Royton, Oldham, and took his first steps as a broadcaster in student radio while at Liverpool University.

The last figures available showed an audience of 7.1million tuning into the show.

Bosses will be hoping Grimshaw, 10 years younger than Moyles who left earlier this month after more than eight years, can bring in listeners from its target 15 to 29 target audience.

Grimshaw told listeners that “I’ve literally wanted to do this job since I was 10 or 11”.

He said he knew his father was proud of him for getting the job “because my mum said ‘he’s gone for a walk”’ and revealed he had messages of support from stars including David Beckham and James Corden.

The show featured a phone interview with Styles - the first of five daily interviews with members of the boyband.
