On July 12, 1979, “Disco Demolition Night,” an infamous promotion at a baseball game on the South Side of Chicago, took place.  Fans who brought a disco record to be destroyed received a game ticket for less than a dollar.  In between the doubleheader of the Chicago White Sox vs. Detroit Tigers, fans stormed the field, and all kinds of mayhem ensued.  The second game of the doubleheader was forfeited to the Tigers–the last forfeit to occur in the American League. This riot was the biggest one by fans at a baseball game since Ten-Cent Beer Night in Cleveland five years earlier.  Coincidentally, a couple of players and an umpire who were at Ten-Cent Beer Night were also present at Disco Demolition Night.
