Poet Benjamin Zephaniah reads his 'Ode to Muhammad Ali', a tribute to 'The Greatest' as the former three-time world heavyweight champion is buried on Friday.
Tens of thousands of people are set to say a final farewell to Ali in his home city of Louisville in Kentucky.
The heavyweight champion and rights activist died last Friday aged 74.
A procession will take Ali's body past key sites in his life, ahead of an interfaith memorial service.
Actor Will Smith and ex-boxer Lennox Lewis will be among the pallbearers, while former President Bill Clinton will deliver one of the eulogies.
