Paul Simon interrupted a performance of his hit song “The Boxer” Friday night to break the news of Muhammad Ali’s death.

The singer was in concert at the Greek Theatre in Berkeley, California.

Toward the end of the song, Simon paused and announced, “I’m sorry to tell you this way, but Muhammad Ali has passed away.”

Members of the audience were audibly saddened by the news, and then joined Simon in singing the final verse of the song, which is about a boxer struggling with his career and personal life.

Paul Simon and his partner Art Garfunkel grew in popularity during the 1960s, the same time that Muhammad Ali did.

Although the duo were not as vocally opposed to the Vietnam War as Ali was, a number of their songs — notably 1966’s “Homeward Bound” — were adopted as anti-war anthems.

“The Boxer” is from Simon & Garfunkel’s seminal 1970 album “Bridge Over Troubled Water.”

Muhammad Ali died Friday after being hospitalized earlier in the week for respiratory problems. Like Simon, he was 74 years old.

Muhammad Ali was born Cassius Marcellus Clay Jr. in 1942 in Louisville, Kentucky. As a young boy, Clay was first introduced to the world of boxing when his red-and-white Schwinn bicycle was stolen. An upset Clay reported the incident to a police officer Joe Martin, who happened to be a boxing trainer, and suggested the boy learned how to fight. Martin went on to become Clay's trainer throughout his six-year amateur career.

Clay won the gold medal at the 1960 Summer Olympics in Rome for light heavyweight boxing, despite almost not competing on the U.S. team due to his fear of flying.

Clay became the heavyweight champion of the world on Feb. 25, 1964, after defeating reigning champion Sonny Liston. It was at this match that Clay coined the iconic phrase “float like a butterfly, sting like a bee.”

The day after the match, Clay confirmed in a press conference that he had converted after joining the Nation of Islam. He renounced his last name and called himself Cassius X until March 6, 1964, when Elijah Muhammad of the Nation of Islam gave him his official holy name, Muhammad Ali.

Ali refused to fight in the Vietnam War for religious reasons -- a decision that led to the New York State Athletic Commission suspending his boxing license and revoking his heavyweight belt. He was also arrested for draft evasion, but the Supreme Court eventually overturned his conviction on June 28, 1971.
