Country-western star Reba McEntire sings "There's No Business Like Show Business" aloft on the shoulders of her Annie Get Your Gun chorus boys. McEntire strutted her stuff for the press, singing "Show Business" and "They Say It's Wonderful" Jan. 9 at New York City's Cowgirls Hall of Fame. Broadway's Brent Barrett (Chicago) will be Frank Butler to McEntire's Annie Oakley in Annie Get Your Gun, beginning Jan. 26. McEntire replaces "Charlie's Angels"' Cheryl Ladd, who followed Bernadette Peters as in the title role.
