On "The Evolution of Encores!", guests Judith E. Daykin (founder), Rob Fisher (music director from founding to 2006), David Ives (book adapter for 18 productions) and Jack Viertel (artistic director since 2001) discuss the growth and success of the acclaimed musical concert series at New York's City Center, exploring how "Encores!" grew out of a concert at BAM in the late 80s; how the international success of "Chicago" impacted the series; how shows are selected; whether the addition of costumes, choreography and other "production" elements have moved the series away from its original goals; and whether there are shows they shouldn't have done or wish they could do again.
