Overtone

Hollywood movie producer Clint Eastwood has reportedly asked an unknown seven-member South African acapella boy-band called Overtone to make a demo for the sound-track for his next movie, which is a biography of Nelson Mandela.

Overtone was talent-spotted by Eastwood's wife Dina when she attended their whacking good tribute show to the late singer Freddy Mercury, called "The Killer Queen", which has drawn rave reviews in South Africa.
