Olivia Newton-John, 'Grease' star and singer, dies aged 73

Australian singer Olivia Newton-John, who gained worldwide fame as high-school sweetheart Sandy in the hit musical movie "Grease," died Monday, her family said. She was 73.
Her husband John Easterling said she died peacefully at her ranch in Southern California surrounded by family and friends.
She had battled breast cancer for many years but a specific cause of death was not given.

Newton-John is best-known for starring in the 1978 musical "Grease" alongside John Travolta, as the-girl-next-door Sandy, who trades her ankle-length skirt and prim and proper hair for skin-tight black pants and a perm.
The high school sweetheart-turned-bad girl resonated with audiences worldwide, and continues to capture hearts decades after the movie was released. 
 'You're the one that I want'
Several songs from the movie, particularly "You're the One that I Want," "Summer Nights," and "Hopelessly Devoted to You" remain all-time favourites.
"Making it was fun but you never know with movies if audiences are going to go with it or not, even if you love it," she said in a Forbes interview in 2018. 
"It is incredible that it is still going but it's not even just that, it's showing no signs of stopping.
