Speaking at the service, former US president Bill Clinton described Muhammad Ali as a man who "decided very young to write his own life story".
He said "before fate and time could work their will on him, he decided that he would not ever be dis-empowered".

Billy Crystal also paid his respects to the 74 year-old, likening Ali's uniqueness to that of Mozart and Picasso.
The actor and comedian said Ali became a "silent messenger of peace who taught us that life is best when you build bridges between people, not walls".
During his speech he also did an impression of 'The Greatest', and received big laughs from the guests.
