Travolta posted a heartfelt message on social media, writing: “My dear Olivia, you have made all of our lives so much better. Your impact was incredible. I love you so much.

Her prominence as an activist for research and better treatment will likely remain as central to her legacy as her showbiz career, which included four Grammy wins and the sale of more than 100 million records. But it was Grease, the lively 1978 adaptation of the Broadway musical, for which she will be most fondly remembered.

A brief career slump followed initial recognition for the album, before Newton-John represented the United Kingdom in the Eurovision Song Contest in 1974. Her song, Long Live Love, finished equal fourth behind Abba’s winner Waterloo. This was followed by a period of singing and recording country music, before being covered in Grease.

A second collaboration with Travolta in 1983’s Two of a Kind fell through, but the pair remained close friends over the following decades and most recently sang together in 2012.
