It’s said that the former heavyweight boxer had been a long-term fan of Tom and would often visit his home while the singer was in the United States.
Despite their friendship, it’s said that one day, Muhammed believed it would be “fun” for Sir Tom to visit his intense training camp for a day.
Speaking of his late friend, Sir Tom said: “Yeah, he was great. He was a wonderful person, very clever, very smart.
“He invited me up to his camp and said, ‘You want to get in the ring?’ I used to box when I was at school, so we got in there, he said, ‘Just throw something’.”
