How do you freshen up a classic like Fiddler on the Roof without disturbing those finely etched images so many have of the show? One can “hardly ignore the special place the show holds in the public’s affections. ‘I told the whole team very early on that I wanted to take care of `Fiddler.’ That’s a phrase I’ve never used before. But there’s already a vast audience that loves the piece, people who will be bringing their children to the theater, perhaps for the first time. And it’s very important not to disappoint.”
