Her romantic dance scene with screen boyfriend Rolfe in a gazebo during a thunderstorm while singing "Sixteen Going On Seventeen" was considered one of the movie's most charming scenes.
After "The Sound of Music," Carr appeared in the TV musical "Evening Primrose" with Anthony Perkins but then stepped back from acting to start an interior design business and raise a family.
But her enthusiasm for "The Sound of Music" remained undiminished and in 2000, she started hosting sing-alongs of the movie across the United States, which drew thousands of fans dressed as their favorite characters.
