This sympathy is not translated into force against the British government because it is not like the anti- apartheid movement which had a high profile here and Mandela is a more engaging figure than Yasser Arafat.

Movies TV sports come and go but what you stand for is what people remember. Mandela Martin Luther King John Kennedy are people who really stood for something and were willing to die for it. You don't see a whole lot of that any more.

Think about all the great leaders. Think about Obama. Think about Clinton. Think about Nelson Mandela. Think about all the people that we know who are very successful in business in politics and religion. What are they? They tell purposeful stories. They move people to action by aiming at the heart.

Before Nelson Mandela was arrested in 1962 he was an angry relatively young man. He founded the ANC's military wing. When he was released he surprised everyone because he was talking about reconciliation and forgiveness and not about revenge.

It was deeply important for me to understand where Mandela came from. Because we know where he was going and that's a famous story but who was he? Where did he come from? What was his upbringing?

As far as those kinds of things I also played at the concert to call for the release of Nelson Mandela when he was a political prisoner in South Africa. We were celebrating his 70th birthday and calling for his release.
