Understood to be a reference to the fall of apartheid. As sung by the Polokwane Choir, taught by Northern Harmony. This is from The OK Chorale's first ever public concert in Woodbridge, Suffolk, UK on 24 March 2012. Not the best of lighting! Also a bit shouty in places as it was many of the singers' first time in front of an audience. www.chrisrowbury.com
