The Sox were 40–46 going into the twinight double-header with the Tigers at Comiskey Park, and the club’s management had invited Dahl to stage the promotion to attract teenage fans. It backfired. When Dahl — who later insisted the stunt was just a bunch of kids “pissing on a musical genre” and not an act of racism or homophobia, as many have come to see it — blew up a crate of disco records, fans streamed from the stands and started tearing up the field. The Sox ultimately forfeited the second game — an enduring stain on the ball club’s history.
