On a sombre day when he viewed Nelson Mandela's body laying in state, Dr Pita Sharples also had an amusing encounter with supermodel Naomi Campbell and Irish rockstar Bono.
Mr Sharples said he climbed on the bus taking the dignitaries to view the body at the Union Buildings in Pretoria and he had sat at the back of the bus.
He saw Bono and Campbell looking for a seat so shouted to them: "Down here, there lots of seats."
He said the two stars came down to the back of the bus and someone suggested Naomi Campbell sit on Dr Sharples' knee.
