Composer Stephen Sondheim will appear at the Harris Theater on March 4 and Broadway star Christine Ebersole on March 25 as part of A Life in the Theater, a series of performances and conversations featuring noted artists.

Sondheim, who turns 80 on March 22, will be interviewed by director Gary Griffin, whose credits range from The Color Purple on Broadway to superb local stagings of Sondheim’s A Little Night Music and Pacific Overtures at Chicago Shakespeare Theater. (Griffin’s production of Noel Coward’s Private Lives is now onstage at CST.) Ebersole, a Winnetka native who won Tony Awards for her performances in 42nd Street and Grey Gardens, will present an evening of Broadway songs and standards with pianist John Oddo.

Sondheim: Thu 3/4, 7: 30 PM, $35-$65, Ebersole: Thu 3/25, 7:30 PM, $45-$75, Harris Theater, 205 E. Randolph, 312-334-7777.
