If Tennessee Williams is in heaven (which I doubt knowing the troubled life he led), mayhap he’ll hear the gentle strumming of his words, from our lips to his ears. And if he is in the other place (which is more likely knowing the troubled life he led) mayhap the music will be so clear he won’t be able to escape it, even there.
A generous reading would presume that "the troubled life he led" refers to, say, Tennessee's problems with drugs and alcohol, and isn't meant as a veiled reference to his homosexuality. No matter what prompts Kelley's suspicions about the afterlife of one of our greatest playwrights, it's surprising to see a theater artist publicly announce such a thing. (One wonders if she has similar thoughts on the whereabouts of O'Neill and Miller. Perhaps she has a list.) It's even more surprising to see Steppenwolf publish such a thing.
