We’re taking a look at duets on this week’s Dress Circle (10/29 7:00 p.m.), and they’re not just for lovers. From shows like “Barnum,” “Napoleon,” “Calamity Jane,” “Strike Up the Band,” “Carousel,” and “Out of This World,” you’ll hear Glenn Close, Jim Dale, Susan Watson, Doris Day, Howard Keel, Jo Sullivan, Robert Weede, Audra McDonald, Brian Stokes Mitchell and others share the ups and downs of all sorts of relationships. Join us for music of times that are happy, wistful, combative, sad, philosophical, and silly. Oh, there will be songs about love too. Join us this and every Sunday, and don’t forget to look for us on Facebook and at www.DCSRO.com.
