Outgoing Radio 1 breakfast host Chris Moyles has recorded a track with chart stars Rizzle Kicks.
The DJ told listeners he had joined the band in the studio to create the knockabout track in which they exchange banter, poking fun at each other's ages.
The Mama Do The Hump hitmakers were also guests on his show today as Moyles hosted his penultimate breakfast slot in front of 200-plus listeners at the BBC's Radio Theatre.
Moyles, 38, was welcoming a series of special guests on the show and his team presented a series of video montages looking back at his period of more than eight years in charge of the prestige morning show.
Moyles will bow out from the show for a final time tomorrow. Fellow Radio 1 DJ Nick Grimshaw is to take over the programme later this month.
