On January 1, 1985, a show including several world champion boxers in exhibition fights was staged in Mexico City, Mexico to garner money for the victims of a 1984 gas explosion in Mexico. Among those who fought were Lupe Pintor, German Torres, Julio César Chávez and Hector Camacho Sr. The latter two would face each other in an actual official fight on September 1992, which Chávez won by unanimous decision.
