When asked what he looks for in the people he entrusts to interpret his work, Stephen Sondheim said In London This week: “Mostly it’s the directors you have to be careful of. Many, many directors, particularly in musicals, are more interested in serving themselves rather than serving the text, because musicals invite a lot of invention. Even if that director is inventive, he or she should be serving the piece, and you don’t always get that. That’s the thing I look for.”
