Editor's note: The Dallas Cowboys won their first-ever Super Bowl on January 16, 1972 with a 24-3 demolition of the Miami Dolphins. The U.S. Air Force Academy Chorale played the national anthem, the Marine Corps drill team joined in on the halftime show, and 81,023 fans came to see the big face-off in New Orleans' Tulane Stadium.Even then, 46 years ago, our Dallas Morning News writers and photographers were at the scene.
