When the news broke that beloved and revered civil rights icon Nelson Mandela had passed, it felt like the entire world took a collective sigh as we mourned the loss of one of the greatest heroes of a generation. The Woolworths in South Africa was planning a Christmastime fundraiser with a flash mob. At the last minute, they dropped the Christmas song they were going to sing and chose to pay tribute to "Tata Madiba." The song they chose is by British musician Johnny Clegg called "Asimbonanga," which was written in the 1980s calling for Mandela's release from prison. I can think of no better way for this flash mob to honor the legacy of a man who for many represented the heart and soul of the fight for freedom.
