Sondheim @ 90 Roundtable, Passion with John Doyle, Judy Kuhn, Kathy Voytko and host Michael Weber at Porchlight Music Theatre

Premiere: Saturday, Jan. 30 at 7 p.m. CST

Sondheim's 1994 musical Passion is the focus of the penultimate episode of Sondheim @ 90 Roundtable. Passion tells the story of a love triangle and is adapted from Ettore Scola's 1981 film "Passione d'Amore" and its source material, Iginio Ugo Tarchetti's 1869 novel "Fosca." Weber's guests this week, discussing what many consider Sondheim's most personal work, are John Doyle (Tony Award-winning director; artistic director of Classic Stage Company), Judy Kuhn (multiple Tony, Olivier and Grammy Award nominee; Passion at the Kennedy Center Sondheim Festival) and Kathy Voytko (Broadway's The Frogs and Chicago Shakespeare's Passion.)
