Happy 90th Birthday, Chicago Theatre!

The Chicago Theatre turns 90 years old on Wednesday. They're celebrating by offering special marquee tours of the landmark theater today through Wednesday. They're busting out the Wurlitzer Organ for a rare, live performance during the tours, too. By the way, the first event at Chicago Theatre back in 1921 was the silent film "The Sign on the Door," featuring a 50-piece orchestra in the pit.

Chicago Theatre, 175 N. State Street, Oct. 24 to 26, 6 p.m., $15 in advance or $12 at the box office.
