July 12, 1979 was a memorable night at Chicago's Comiskey Park. During games of a scheduled double-header between the White Sox and visiting Detroit Tigers, Chicago radio DJ Steve Dahl hosted an event known as Disco Demolition.

The chaos that followed the blowing up of disco records after fans mobbed the field caused the second game to be cancelled.

Major League Baseball has now embraced this quirky incident in its history by adding the war helmet Dahl donned that night to its permanent collection at the Hall of Fame in Cooperstown. The host shared the news on his Facebook page recently.
