Ray Charles At The 2nd Sugar Ray (Charles) Leonard Vs. Roberto Duran Fight (1980)

Sugar Ray Leonard (born Ray Charles Leonard, named after the singing legend, on May 17, 1956) is widely considered to be one of the best boxers of all time, winning world titles in multiple weight classes. In the first fight against Roberto Duran Leonard went to the Olympic Stadium in Montreal to defend his world title. Duran etched out a close but unanimous decision, inflicting Leonard his first loss. Leonard came back for a  rematch in the New Orleans Superdome on November 25, 1980 - a new man with a new plan. He outboxed Duran, frustrating him from the opening bell, and with 17 seconds to go in round 8, the unthinkable happened: Duran turned around, walked to his corner and gave up, saying the now worldwide famous words of "No más!" Referee Octavio Meyran , perhaps incredulous as was the rest of the world of what he was seeing, asked Duran if he was sure, and Duran repeated himself again: "No más, no más!"

Before the fight Ray Charles sang America The Beautiful.

From a comment on YouTube:

"Closed circuit TV was an early Pay Per View. But then, you didn't have cable or satellite, so people would go to an arena and pay to watch the telecast there. It was a lot of fun to watch the fight with a lot of other fans in the coliseum. This fight was shown in arenas around the country."
