One challenge facing the city is how to reduce the number of people, including kids, who are homeless in Chicago. It’s a challenge Ed Shurna has been tackling for nearly two decades while working at the Chicago Coalition for the Homeless. On the eve of his retirement, he talks about the changes he’s seen over the years. Another challenge is determining how to increase the number of new priests in the Catholic Church. The man in charge of recruitment for the Archdiocese of Chicago explains how the church here is taking on that task. Plus, we share another installment of the series My Life in Three Songs with Rabbi Jonathan Sacks sharing his picks. And we enjoy live music from Chicago's eclectic indie band Marrow. Plus we check in with two WBEZ Bureau Reporters about the latest in the cases of two police-involved shootings in Chicago.
