Cantigny Park’s Robert R. McCormick Museum welcomes Rabbit Ears, a flute and guitar ensemble performing light classical music such as Bach, Beethoven and Handel as well as favorites by Cole Porter, George Gershwin and Irving Berlin. Tickets are free, but distribution is by lottery due to limited seating in the museum’s historic Freedom Hall. Those wishing to attend should call 630.260.8162 or email firstname.lastname@example.org by Feb. 8. E-mails should include a phone number. Cantigny will draw 40 names and contact ticket recipients by Feb. 13. Each winner will receive two tickets.
