Ben Brantley gushes over Headley (and Marin Mazzie) in a column on replacements in long-running revivals:
“Push the Button,” the honky-tonk number in which Shug demonstrates the art of pleasing a partner in bed, is now the raging showstopper it should be. Yet Ms. Headley’s Shug is also fiercely vulnerable, on prickly guard against those who might discover her soft spots.
When she finds herself unexpectedly falling for the plain and work-worn Celie, her long body morphs from sharp angles into melting curves. And her resplendent voice matches her mercurial character’s every emotional shift. As important, it also blends beautifully with Ms. Erivo’s, and their climactic first-act duet becomes a tender, erotic intermingling of kindred spirits.

"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
