For the last 40 years, Walt Whitman and the Soul Children of Chicago have been traveling the world to share their love of music.

Wednesday, they’ll celebrate their 40th anniversary in a special concert in Grant Park — featuring current and past members of the choir.

Arts Correspondent Angel Idowu stopped in on their rehearsal to get a taste of what to expect.
