Legendary jazz trumpeter Hugh Masekela, a leading figure in the struggle to end apartheid and "the father of South African jazz", has died aged 78.
"After a protracted and courageous battle with prostate cancer, he passed peacefully in Johannesburg", Masekela's family said in a statement.
"Mr Masekela was one of the pioneers of jazz music in South Africa whose talent was recognised and honoured internationally over many years".
The 1977 song became synonymous with the anti-apartheid movement.
