As a new production of the global hit musical, Mamma Mia, opens at Stephens College in Columbia, show host Diana Moxon chats to the Dean of the Performing Art School, Dr. Gail Humphries Mardirosian and actors Natalie Irlmeier (Sophie) and Jeffrey Keller (Sky) about hitting the high notes, singing while keeping your balance on a revolving bed, and the joys of working with a director who performed in Mamma Mia on Broadway. And in the second act of the show, the Missouri Symphony Orchestra's new Executive Director, Trent Rash, and Development Director, Monica Palmer, talk about their plans for the symphony, how to make classical music cool, and the legacy of Maestro Hugo Vianello. As usual Diana rounds out the show with a rundown of some of the arts events coming up in and around Columbia over the next 7 days.
