Country-western star Reba McEntire will get her gun in the Broadway revival of irving Berlin's Annie Get Your Gun starting Jan. 26. She strutted her stuff for the press, singing "There's No Business Like 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. McEntire replaces "Charlie's Angels"' Cheryl Ladd, who followed Bernadette Peters as in the title role.
