Actor Billy Crystal and Rabbi Michael Lerner are set to speak at Muhammad Ali’s funeral on Friday.
The boxing legend, who was a political, sporting and religious inspiration to millions, died on June 3 after living with Parkinson’s disease for more than 30 years.
Mr Crystal, a Tony award winner and Hollywood star, performed at Ali's retirement tribute in 1979, making the three-time heavyweight champion of the world laugh uproariously during his impression-laden recap of the boxer’s life, titled “15 Rounds”.
The comedian posted the clip to Twitter on Friday, just after news broke of Ali’s death, with the message: “For the greatest man I have ever known.”
