In the 1980s, Bi Kidude burst onto the international music scene, when she was in her 70s. She was one of the first women from Zanzibar to sing in public without wearing the veil, in the traditional Muslim country.

She was born Fatuma binti Baraka, known as Bi Kidude or "little madame" in Swahili, and fondly referred to as the "golden grandmother of music".

Maryam Hamdani was one of her oldest friends and helped launch Bi Kidude's career globally. Maryam spoke to Reena Stanton-Sharma about the charismatic musician who died in 2013.

On 14 September 2013, the Arctic Sunrise - a ship belonging to the environmental group Greenpeace - embarked on an Arctic expedition.

Its aim was to disrupt the first day of drilling on a newly built oil rig.

This would be the first to drill for Arctic oil - something that had only been made possible in recent years by melting ice in the region.

Frank Hewetson, a Greenpeace campaigner, was on board. He tells the story of the protest and arrest of 30 people by the Russian authorities.

Launched in 1966 by Communist leader Mao Zedong, the Cultural Revolution plunged China into a decade of chaos. The education of millions of young people was disrupted and China was cut off from the rest of the world.

When students first started venturing out, it was still a country feeling the after effects of the Cultural Revolution.

Farhana Haider spoke to writer Zha Jianying in 2021. She was one of the first batch of Chinese students to arrive in the USA in the early 1980s.

In 2000, an expedition to the Mexican island of Guadalupe launched a fight to save its ecosystem from being eaten by goats.

Russian whalers had introduced the goats to the island in the 19th Century and the population exploded as they ate their way through Guadalupe’s plants, shrubs and trees.

Several species of birds were already extinct when a group of scientists, from the San Diego Natural History Museum, visited to inspect the damage.

Their expedition would begin the campaign to save the island’s wildlife from extinction, as Professor Exequiel Ezcurra tells Jane Wilkinson.

Sixty years ago, there was a boycott of local bus services in the English city of Bristol. The bus company had specified that it did not want to employ black bus drivers.

The boycott ended on 28 August 1963 and the campaign helped to bring about Britain's first laws against racial discrimination.

In 2013, Louise Hidalgo heard from Paul Stephenson and Roy Hackett, who died in 2022.

This programme contains some racist language, used at the time.
