Capetown, Jo’burg, Soweto
Freedom come, apartheid go

COSATU, ANC*
People set Mandela free

Many years. Long, long time
Weary people & a sleeping lion

Black & white, destiny
Live together in harmony

Poor say yes!  Rich say no!
Where in the world did Botha go?

Finest sight I ever se
Tutu dancing, Mandela free!

Nelson Mandela (1918-2013) was the long-term leader of the African National Congress. Mandela was imprisoned in South Africa from 1964 to 1989. The prosecution had asked for the death penalty but instead Mandela was sentenced to life in prison for sabotage and advocating violent overthrow of the government. He was subsequently elected president of South Africa in the first open election with universal suffrage. https://en.wikipedia.org/wiki/Nelson_Mandela
