Powerful: The Bulawayo Church Choir ad "Wangal' Unozipho"

Today's random tune, Wangal' Unozipho by the The Bulawayo Church Choir, is from The Power of One movie soundtrack. I don't know much about the group, and I couldn't find too much information either, other than that they are from South Africa. I did see the movie many years ago. The Power of One is based on a novel by Bryce Courtenay and is the story of a young English boy in South Africa and his complicated relationships under apartheid with others in the country, black and white. The Power of One soundtrack was released in 1992.
