Take a listen to these minutes: what did you imagine when you listened?
Two of these minutes were written to remember the people who were affected by World War Two. The other one was recorded in 1942 during the war, and you can hear the rumbling of bomber planes in the background.
World War Two lasted from 1939 to 1945 and was fought in Europe, North Africa, Asia and elsewhere.
It was fought between two main groups of countries. On the one side was Germany, Italy and Japan (the axis powers). On the other were the Allies, which included Britain, France, Australia, Canada, New Zealand, India and the Soviet Union.
Tragically, millions of people died during the war and families across the world were affected, particularly Jewish families during the Holocaust.
