The shocking event, which insiders say may be linked to Stacy’s history of cocaine abuse, occurred in Chicago before an opening-night audience for "Pamplona," a one-man show about legendary author
Ernest Hemingway. As the play approached the final scenes, Stacy, who starred as a tough-guy private eye in, "Mickey Spillane’s Mike Hammer," began repeating his lines. Chicago Tribune theater critic
Chris Jones said he knew something was wrong, “when you began to hear lines repeated over and over again.”
