The revival at the Goodman this summer actually used different text. I truly cannot recall what it was, but Eulalie led something completely unrelated and non-appropriative. Surely a theatre of their stature would have secured permission for such a change, so I would definitely contact the licensing agency and ask if there is any alternative text you can use, perhaps citing the Goodman's production as precedent. If it got approved once, surely it can get approved again.
