On the radio: Sondheim & Rich

Here's some good news for those of us shut out of the City Arts & Lectures event at which former New York Times theater critic Frank Rich (aka "The Butcher of Broadway") interviewed Stephen Sondheim at the Herbst Theatre.The show, edited down to an hour, will be on KQED radio (88.5 FM) at 1 p.m. June 1 and 8 p.m. and 2 a.m. June 3.I'll be listening. From friends who went to the show, I learned that Sondheim is intrigued by the notion of turning the Bill Murray movie Groundhog Day into a musical -- something about the repetition of the days lending themselves to musical interpretation. Sort of makes sense.Visit the City Arts & Lectures Web site for information: www.cityarts.net.
