Members of the Soweto Gospel Choir posed as customers and shop workers in the Woolworth's Parkview store in Pretoria to sing this tribute to Nelson Mandela. The song is Johnny Clegg's Asimbonanga, written during Mandela's inprisonment as a call for his freedom. Beautifully sung - definitely real music - and it's a pleasure to see the reactions of all the customers. I just can't see it happening over here in Tesco's though. There's a translation here.
