A compilation of this week's Witness History episodes. Gerald Clarke, the author of Get Happy: The Life of Judy Garland, speaks to Max Pearson about the legacy of the stage and screen actress who died in 1969.

We also look at how a chance encounter led to the return of two of the looted Benin Bronzes, ancient artworks which were among thousands stolen from Benin City by the British Army in 1897.

And we head back to 2008, when a nine-year-old boy tripped over a fossil that would lead to one of the most important discoveries in the history of human evolution.
