I had the opportunity to be here on the day all the stars came out to pay tribute to Nelson Mandela.I have to say the greatest surprise for me was to witness the amazing talent of Whitney Houston. I must confess that i was not the greatest fan of hers until i had the honour of hearing that Gospel influenced voice of hers. I have never been so mesmerized by any singer before or for that matter since.Her vocal ability, strength and range completely commanded the 100,000 strong crowd.For me it was incredible to witness such an amazing performance.Anyone who appreciates the human voice as an instrument.......this is one moment not to be missed.Whitney was the star among stars.
