Portrait of, from left, American disc jockey (from WLUP radio, 'The Loop') Steve Dahl (in helmet), model Lorelei Shark, and Mike Veeck, the son of the Chicago White Sox owner, during an anti-disco promotion at Comiskey Park, Chicago, Illinois, July 12, 1979. The event, hosted by Dahl and held between games of a doubleheader between the Chicago White Sox and the Detroit Tigers, allowed fans to attend the games for 98 cents along with an unwanted record and, following the detonation of those records, eventually resulted in the White Sox forfeiture of the second game due to unsafe playing conditions when fans stormed the field causing serious damage to the venue and playing surface.
