Touted on show's website as 'some of the greatest voices of our generation' (Is Audra McDonald of our generation? How about Marilyn Maye?), Candice Glover ('American Idol' Season 12), Josh Kaufman ('The Voice' Season 6) and Bianca Ryan ('America's Got Talent' Season 1, when she was 11) are, in all seriousness, at least reasonably talented. And again, in all seriousness, this New York theatre critic probably has no business critiquing their vocal capabilities, since they're of a style he rarely pays attention to. But their show is on Broadway, so it's the responsibility of a Broadway theatre critic to see and review it.
