NEW YORK — The official tongue-in-cheek slogan for “The Book of Mormon” claims that it is “God’s Favorite Musical.” Producers of the show are hopeful the Broadway community agrees. The satirical show goes into Sunday night’s Tony Awards with 14 Tony nominations, one shy of the record held by “The Producers,” and is heavily favored to nab at the very least the best musical crown. The show, by the creators of “South Park” and “Avenue Q,” has already been declared the season’s best musical by the Outer Critics Circle, the Drama League and the New York Drama Critics’ Circle.
