For many folks both in and out of Chicago, columnist Mike Royko embodied our city with his wit, his prose, and his skills as a reporter. From the mid-1960s into the 1990s, he churned out a daily newspaper column that poked politicians, skewered stupid ideas, razzed the rich and spoke for the “everyman” in Chicago’s neighborhoods. His unauthorized biography of Mayor Richard J. Daley and his political machine “Boss” is considered a nonfiction classic. But as much as we believed we knew the man through his columns, he rarely granted interviews. In 1994, three years before Royko’s death, then-WBEZ host Chris Robling sat down with him for a wide-ranging interview.
