Newton-John was the daughter of German literature professor Brin Newton-John and Irene Bron, whose father was Nobel Prize-winning physicist Max Bron. The Newton-Johns moved to Australia when Olivia was 5, but she returned to England in her teens and lived with her mother after her parents broke up. She had early dreams of becoming a veterinarian but was winning singing contests in high school and before age 20 had toured army bases and clubs and recorded her first single, “Till You Say You’ll Be Mine.” In 1971, she covered Bob Dylan’s “If Not for You” and began a close partnership with a friend from Australia, John Farrar, who produced the song and later wrote “You’re the One That I Want,” “Magic” and several other hits for her.
She had loved country music, especially the records of “Tennessee” Ernie Ford, since childhood, but her early success didn’t impress critics or some fellow musicians. A Village Voice review likened her to a geisha who “makes her voice smaller than it really is just to please men.” When Newton-John beat out Dolly Parton and Loretta Lynn for the Country Music Association’s top artist of 1973, Tammy Wynette helped founded the Association of Country Entertainers, a club designed to exclude Newton-John and other crossover performers.
But Newton-John had a show business admirer who with her became one of movies’ most unforgettable teams. Travolta had starred in the stage version of “Grease” and for the planned film thought Newton-John would be the “ultimate” Sandy, the nice girl who gets tough in the final act and gets her man.
“I worried that at 29 I was too old to play a high school girl,” Newton-John, who insisted on taking a screen test before accepting the part, told The Telegraph in 2017. “Everything about making the film was fun, but if I had to pick a favorite moment, it was the transformation from what I call Sandy 1 to Sandy 2. I got to play a different character and wear different clothes, and when I put on that tight black outfit to sing ‘You’re the One That I Want,’ I got a very different reaction from the guys on the set.”
She is survived by her husband; daughter Chloe Lattanzi; sister Sarah Newton-John; brother Toby Newton-John; and several nieces and nephews.
