At the Act One climax of Finian’s Rainbow, which premiered 75 years ago, Billboard Rawkins, a bigoted white Southern senator, turns into a black man by the power of a wish. There’s a blackout, and the actor playing Rawkins hurriedly smears blackface on. Obviously you can’t get away with that anymore, and these days, if anyone dares to do Finian’s (they should), there’s a blackout, and a black Rawkins rushes on to replace the white one. However, in the Act One climax of Black No More, a new musical adapted from George S. Schuyler’s 1931 satirical novel, an opposite racial transition happens.
