"Postgate's work is deep inside me and I think that's true for so many of my generation...His work represents nothing less than a touchstone for our national imagination and in that sense it's profoundly important"

Andrew Davenport, writer, composer, and creator of Teletubbies and In the Night Garden, nominates Oliver Postgate, who, along with his Smallfilms business partner, the artist Peter Firmin, invented the children's television shows Ivor the Engine, The Clangers and, perhaps most loved of all, Bagpuss.

Postgate was a late bloomer. Following Dartington school (which he hated) a stint in jail and working the land, several odd jobs and even odder inventions, he eventually discovered a love of stop-motion animation and created some of the most enduring worlds and best-loved characters in television, all from a cowshed in Kent.

Including clips of his programmes, contributions from singer and musician Sandra Kerr. and archive from Postgate's 2007 Desert Island Discs interview.

With cultural historian Matthew Sweet. Produced by Ellie Richold. Presented by Matthew Parris.

Lucy Jones, author of Matrescence, chooses the writer Sylvia Plath.

Sylvia Plath was a precocious, prize-winning child,. Her mother had high expectations for her. Her father had died when she was 8 (but could have been saved if only he'd gone to see a doctor).

When she was well, Plath was energetic, fun, bright, attractive, funny and incredibly smart.

Her first depressive episode at the age of 20, was 'treated' with botched electric shock therapy. She was awake throughout the ordeal, which left her terrified and traumatised.

Lucy Jones believes that Plath has an unfair reputation as a depressing writer, because of the shadow that her suicide casts backwards over her life. But Jones finds Plath's poetry incredibly alive, brave, comforting and inspiring. "I don't think I would have been able to write Matrescence without Plath's work"

Both Lucy Jones and Plath's biographer, Heather Clark, believe that at the end of her life, recently separated and struggling through a particularly bad winter with two very small children, she may have been suffering from post-natal depression.

With archive recordings of Sylvia Plath reading her poems Daddy and Mushrooms, as well as being interviewed with Ted Hughes.

"The area I mostly work in is generally known as free - the free music area. And free is one of those four letter words, like rock or jazz or punk maybe. It started out meaning something." Derek Bailey

Born in 1930 in Sheffield, Bailey worked as a session musician in dance bands and orchestras before turning his back on that world. Free improvisation was where he made his name, and he took inspiration from whatever he heard. Stewart Lee first heard him in the 1990s and spoke at his funeral in 2005.

"Are there any parallels between his approach and yours?"

Also contains the voices of Ian Greaves and Tim Fletcher, a brief clip of Mastermind, and a recording of Derek Bailey's collaborator in the Joseph Holbrooke Trio, Gavin Bryars. Stewart Lee is a comedian and writer, the presenter is Matthew Parris and the producer for BBC Studios is Miles Warde.

We regret that this description barely scrapes the surface of the wonder of this episode - the ideas, the music, the archive, the brief row.
