Carr's contribution to "The Sound of Music" was huge — she sang the beloved song "Sixteen Going on Seventeen." At the time, she was actually 21 going on 22.
"Julie Andrews was so kind to me," Carr said in a TV interview. "It's been a wonderful, wonderful part of my life... It's really a wonderful feeling to know that you've been in a film that's affected so many people, that has made them so happy. It's better than, you know, 'The Terminator,' or things like that. If you're gonna do one movie, I think I chose the right one to do."
Carr is survived by her children and grandchildren, a niece, and four siblings.
