Cassius Clay defeats Henry Cooper via TKO in round 5 of their heavyweight fight, comments by Englishmen, pre-fight interviews with both Henry Cooper and Cassius Clay.                        

On HY GARDNER SHOW, an excerpt replay of Heavyweight boxer Cassius Clay's (Muhammad Ali)  interview by WOR-TV sports reporter Clure Mosher, originally broadcast the middle of May 1963 prior to Clay flying to London to fight reigning British Heavyweight Champion, Henry Cooper. 

Cassius Clay tells Clure Mosher that he wants to fight "the bear" Sonny Liston. He states, "I want him three months after Patterson. I'm going to get this man out of the way. He is nothing."

Mosher replies, "Liston is a big, stern and mean-looking man, Cassius. I fear he would just scare you to death getting in the ring with him."

Cassius Clay, "I'm just too crazy to be scared."

Clure Mosher, "I think you're going to do very well and make a lot of money. And, as a matter of fact, you and Patterson may go down in history, as far as I am concerned, as being two of the boxers around having made more money with less talent than anybody."

Cassius Clay, "You are just getting off the subject. You just talk too much. I'm sorry I have to go to bed. I have a fight coming up and I don't want to see you unless I'm in the ring. I'm through."

 Clay walks out on the interview.

After television viewers, Hy Gardner, and his guest views this clip Hy Gardner is amazed at what we just saw.
 
Hy Gardner, "Did you ever see anything like that?" Now, this was Cassius Clay. I don't know if he just got mad and walked out or this was just showmanship?"   

Hy's guest, Brian Wilson (?) on his show remarks that he thinks it was showmanship. Gardner remembers only one time that a guest on his show quit on him on the air, naming Charles Laughton.  

Gardner, "I think it is great when someone does walk out on you. Is this the real  Cassius Clay or Cassius Clay the image?"  

Hy Gardner's guest, Brian Wilson (?) mentions that he recently spent three days in Miami with Clay and thinks he is great for boxing predicting nine out of ten times the round he will beat his opponents. 

Hy comments that during the Clure Mosher interview Clay amazingly called the exact round he would defeat his next opponent.
