Part One- We preview this Sunday afternoon's concert by the Kenosha Chamber Choir: "Songs of the American Heart Beat." The concert will be happening at Bradford High School Auditorium at 3:00. We speak with Michael Gutierrez, who co-directs the group with his wife Michelle, and Agnes Gray, who is president of the group and a member of the soprano section. Part Two- We speak with Phyllis Karas, author of "Curse of the Blumenthals." Karas's book is a product of her obsession with learning all that she could about two tragedies in her family's history - a car accident in 1935 involving a drunk driver that killed six of her relatives - and an incident in 1954 in which a relative of hers committed a brutal murder that became a sensationalized news story.
