In the aftermath of World War Two pesticides and chemical fertilisers started to become more widespread in the UK. Worries about the effect this would have on soil quality led Lady Eve Balfour to establish the Soil Association to promote natural farming techniques. John Butler has been a farmer all his life and he has been speaking to Dina Newman about Lady Eve and the early days of Britain's organic farming movement.

In 1959 the German artist Gustav Metzger came up with a new and subversive form of art. He called it auto-destructive art. It was art as a political weapon and a challenge to the established status quo. Metzger, a survivor of the Nazi Holocaust, organised a series of events in London, called the Destruction in Art Symposium, DIAS, and invited radical artists from all over the world, including a relatively unknown young Japanese American, Yoko Ono.
Mike Lanchin has been hearing from Welsh artist Ivor Davies, who helped Metzger launch the events and was himself an early pioneer of auto-destructive art.

The first play on Broadway written by a black woman
'A Raisin in the Sun' opened on Broadway in 1959. It had an almost exclusively black cast and a black director too. The playwright, Lorraine Hansberry, based it on her own family's story of being forced out of a white neighbourhood in Chicago. The title is from a poem by African American poet Langston Hughes about a dream deferred - 'does it dry up like a raisin in the sun?'.

Dennis Tito - the first space tourist
In April 2001 an American multi-millionaire paid Russia's space agency millions of dollars to blast him into space. He spent time on the International Space Station and returned to earth after eight days in space. Dennis Tito, who was 60 years old at the time of his space flight, spoke to Louise Hidalgo in 2011 about his experiences. (This is a rebroadcast)

Chinese restaurant syndrome
Diners at Chinese restaurants in America in the 1960's began to report unusual symptoms, including headaches, flushing, numbness at the back of the neck.
It was linked to the man-made flavour enhancer monosodium glutamate or MSG – but it was also part of wider attitudes towards Chinese restaurants at the time.
Lucy Burns speaks to restaurateurs Philip Chiang and Ed Schoenfeld about their memories of what became known as 'Chinese restaurant syndrome'.
