Zambian president Kenneth Kaunda paid a lengthy tribute to Nelson Mandela's life, interspersed with humorous quips and a crowd-pleasing jig to start.
"This great son of the world - not only of South Africa - Madiba showed us the way. Whether you are white, black, yellow or brown, you are all God's children," he said.

He also thanked Winnie Mandela for her life's work with her former husband.
