BBC Radio 2 is to refresh its evening schedule on the network from April, launching a new jazz show with Jamie Cullum on Tuesday night and moving Desmond Carrington to Friday.
Both of the new shows will be broadcast between 7pm and 8pm.
Desmond's show will continue to be broadcast live from his home in Perthshire so he can benefit from his unique record collection of more than 250,000 discs. It will lead into an extended Friday Night Is Music Night between 8pm and 10pm.
Desmond said: "When I was asked to introduce a record programme in 1981, the contract was for three months … that three months will soon be 30 years! Thank you, Radio 2, for keeping me young."
Bob Shennan, Controller Radio 2 and 6 Music, said: "Desmond has been a valued part of the Radio 2 story for many years… [He] has fantastic appeal across the ages and I hope that his listeners will continue to enjoy the programme in its new slot."
The UK’s biggest-selling jazz artist of all time, Jamie Cullum, starts his own programme on Tuesday night but is already familiar to the Radio 2 audience. He has presented a number of documentaries and performed with Norah Jones for the launch of Weekend Wogan.
The show will be a one-stop jazz shop featuring guest interviews, live performances and news from the jazz world.
Jamie said: "It's an extraordinary privilege to be able to present an hour of jazz and jazz-related music at such a civilised hour. We're going to present a show that will excite people's ears and bring them into a scene they may not know about."
On this show, Bob Shennan comments: "Radio 2 is proud to demonstrate a continued commitment to jazz by announcing this brand new show. I look forward to Jamie unearthing burgeoning jazz stars of the future, as well as shining a light on the jazz world on a weekly basis."
