Audra McDonald stopped by The Late Show on June 11 to chat with host David Letterman about everything from her Tony-winning turn as Billie Holiday in Lady Day at Emerson’s Bar and Grill to passing out on stage. Wait, what? Turns out the six-time Tony winner didn’t always tread the boards so sure-footedly, although she's "fortunately gotten over that now." We'll say! Find out all this and, touchingly, why McDonald is “so very grateful to my grandmother” for helping her performance as Holiday below, then check out the newly extended play at Circle in the Square.
