Mark Goodier sits in and Sara Cox picks her Tracks Of My Years

Mark Goodier sits in with the mid-morning music quiz Ten To The Top.

Plus, Vernon pops up for the third part of this week's Tracks of My Years with Radio 2 Breakfast Show host Sara Cox. As Sara launches her new Breakfast Show, today she tells us about joining Radio 1 and interviewing Missy Elliott.

Sara was born in 1974, the youngest of five, and spent much of her childhood on her dad's farm where a love of animals has stayed with her ever since. She became a model after being scouted during a trip to Paris, then successfully auditioned for her first presenting role, fronting Channel 4's The Girlie Show. Then followed more TV work followed by joining Radio 1, where she hosted the Breakfast Show from 2000 to 2003. Around a decade later she first joined Radio 2 where her shows have included Sounds Of The 80s and most recently her weekday teatime show. Last year she ran an incredible 135 miles across five days and raised £11.7 million for Children In Need. On 6 July she'll take over the Radio 2 Breakfast Show, bringing all your favourite bits from the afternoon, alongside plenty of brand-new breakfast treats to start your day.
