Richard Branson: I’m optimistic because I think the global community is moving in the right direction. The concerts that took place prior to Nelson Mandela’s release, people like Peter Gabrielle, the songs like Steve Biko, that saw Mandela’s release, that brought about the end of apartheid, those great concerts were a sign of the times. I think that wonderful concerts are taking place on global warming and concerts, that’s the sign of the times. It shows that the people are now wanting their voices to be heard and governments are going to have to listen.
