Max Pearson presents a collection of the week's Witness History interviews from the BBC World Service.

Our guest is Dr Nivi Manchanda, a reader in international politics at Queen Mary University in London.

First, a moment when two cultures clashed in 1985 at Stonehenge.

We hear about an English language novel from 1958, called Things Fall Apart.

Then, the 1992 creation of the iconic Champions League anthem.

Plus, how police raided the popular but controversial file-sharing website The Pirate Bay in 2006.

Finally, how Canadian rock band The Tragically Hip went on one final tour, after their guitarist was given months to live in 2015.
