TODAY’S RADIO

Graham Norton 10AM, RADIO 2

Tom Chaplin, the baby-faced singer with an angelic voice, joins Graham in the studio this morning. Tom was born into a stable family, and found fame and fortune with the band Keane. He also found darkness – and an addiction that nearly killed him. Tom pulled back from the brink, and pursued a solo career. He has a new album out called Twelve Tales Of Christmas, and gives us some songs from it.

The impressionist and comedian Jon Culshaw, the chef Rick Stein and the chat show host Michael Parkinson are also on the show.

Zoe Ball

3PM, RADIO 2

The Sledge family has been in show business for nearly a century, with talent in every generation. Sister Sledge, the disco queens who have sung before Popes and Presidents, notched up decades of hit songs, but suffered the terrible loss of Joni Sledge in the spring of 2017. Debbie and Kim, who are determined to keep the Sledge name in lights, join Zoe this afternoon to talk about their UK tour, which will get on the road in the spring of next year. The Marriage Of Figaro 6.30PM, RADIO 3

The letter duet, which was used so movingly in The Shawshank Redemption, is just one of the many gorgeous pieces of music in this work by Mozart, which comes from New York’s Metropolitan Opera.

Lenny Henry On Richard Pryor

8PM, RADIO 4

The comedian Richard Pryor started his career in New York in the 1960s, serving up a safe routine that he later described as ‘white bread’. Pryor earned good money with this act and took it to Las Vegas, but turned his back on it when he underwent an artistic and political transformation. Drawing on some little-heard archive tapes, Lenny Henry charts Pryor’s journey from being a safe, middle-of-the-road crowd-pleaser to becoming an edgy, sharp comedian with a serious message. The Echo Chamber 11.30PM, RADIO 4

Paul Farley presents a selection of new poems on the subject of total darkness for this time of year, when the nights are long. SJ
