TODAY’S RADIO

Graham Norton

10AM, RADIO 2 Rick Astley is on today’s show to talk about his album 50, which was released this summer. It was Rick’s first number one album since his 1987 debut, Whenever You Need Somebody. Joanne Froggatt shares news of her latest period drama – she’s swapped the corridors of Downton Abbey for bleaker surroundings as she takes on the role of the Victorian murderess Mary Ann Cotton in ITV’s Dark Angel. Tom Goodman-Hill and Gemma Chan will also be dropping by to talk about the new series of Humans.

The Song House

2PM, WORLD SERVICE Fishermen at sea off the Outer Hebrides would sing psalms at twilight, letting their harmonies float across the water. The music they made comes from an ancient tradition; listening to it makes your spine tingle. Ken Hyder plays some of this style of singing, which he believes to be one of the musical wonders of the world, and hears how, in the Outer Hebrides, they struggle to keep the tradition alive.

Dermot O’Leary

3PM, RADIO 2 Madness, who’ve got a new album out called Can’t Touch Us Now, join Dermot for a live Saturday Session. The band The Slow Show – whose music can be sparse, intense and genuinely original – will also be on the show with tracks from their new album, Dream Darling.

Alex James’s Date Night

7PM, CLASSIC FM The ink was still wet on Mozart’s score for the overture for Don Giovanni when the orchestra finally got hold of it; this brinkmanship left the musicians no time to rehearse this key piece for Mozart’s epic opera of Hell and damnation. Alex James marks the anniversary of the opera’s nerve-stretching premiere on tonight’s show.

Fright Night: Rosemary’s Baby

10PM, RADIO 4 Peer through the darkened window, make sure no one’s out there, tiptoe back and settle down as Kim Cattrall sets out to scare the living daylights out of you. She’ll be reading Ira Levin’s tale of the Devil and dark doings in modern Manhattan, which lead to a monstrous birth.
