Colin Powell, hip-hop artist.
America's former top diplomat took centre stage along with Nigerian group Olu Maintain at the Africa Rising Festival in the Royal Albert Hall.
Is there anyone whose reputation was more tainted by association with the Bush administration than Powell? At one time he was on the short list of serious presidential candidates. It's not hard to imagine him running instead of McCain or Palin had things gone better. Even now McCain/Powell would be more interesting - and certainly more credible.
