In conjunction with the Field Museum’s exhibit “Jacqueline Kennedy: The White House Years,” Live Bait Theater restages Edward Thomas-Herrera’s 1995 adaptation of social secretary Letitia Baldrige’s memoirs. “History is often a matter of the simple and everyday,” she says, then proceeds to make her point by offering personal accounts of situations when national and international goodwill was facilitated–or threatened–by such factors as wardrobe, party refreshments, and diplomatic gifts. In this chamber reading, Laurie Larson reprises the role of Baldrige while the rest of the ensemble replicates the icons of the period, giving them an uncaricatured dignity. This is a riveting behind-the-scenes look at events that shaped the country and at a First Lady with a continuing legacy. Through 5/1: Sat-Sun 2 PM. Field Museum, 1400 S. Lake Shore Dr., lecture hall 1, 312-665-7400. $14-$16. Then 5/5-5/15: Thu-Sat 8 PM, Sun 3 PM. Live Bait Theater, 3914 N. Clark, 773-871-1212. $14-$16.
