What began as an effort to sell seats at a White Sox/Detroit Tigers double-header turned into a mass anti-disco movement that would later be credited as the official “day that disco died.” Fans were encouraged to show up with an admission of $0.98 and a disco record that would be blown up at center field between the games; chaos ensued when an estimated 90,000 baseball fans and listeners crammed the ballpark, the surrounding neighborhood streets and the Dan Ryan expressway, creating traffic jams for miles.
Leading the fans in a “Disco Sucks” chant, Dahl headed out to center field in military regalia to blow up the thousands of disco records that had been brought to the ball park for the rally. What he didn’t anticipate was that tens of thousands of eager fans would storm the field. Announcer Harry Caray tried to calm the crowd by leading the park in the singing of “Take Me Out to the Ball Game,” but order could not be restored, and the White Sox were forced to forfeit the next game. Because American League games are virtually never forfeited or cancelled ESPN dubbed Disco Demolition as “One of the Top Ten Most Shocking Moments in Baseball History.”
Dahl admits that the cultural phenomenon that sparked the end of the disco era began simply as his response to losing a job at a radio station that had turned to an all-disco format. Even though disco music had become the unofficial soundtrack of the 1970s, his “disco sucks” mantra struck a nerve because so many Midwesterners simply didn’t ‘get it.’
