When I was in Primary School, I remember hearing a song that was a tribute to Nelson Mandela that used to be played in the assembly's as everyone was entering. It sounds sort of tribal like, the main vocalist is female, and the only line I can remember goes something like: 'black blood flows from a white man's gun', although that might not be strictly correct as it was a long time ago.
Does anyone recognize this description, and name the song for me?
