Olivia Newton-John: Singer Who Became a Country-Pop, Folk-Pop, Rock-Pop, Disco-Pop Sensation in the 1970s

From a Washington Post obit by Adam Bernstein headlined “Olivia Newton-John, pop singer and ‘Grease’ star, dies at 73”:

Olivia Newton-John, the dulcet-voiced singer from Australia who became a country-pop, folk-pop, rock-pop, disco-pop sensation in the 1970s, starred in the Hollywood musical juggernaut “Grease” and underwent a sultry makeover with her mega-selling 1981 record “Physical,” died at her ranch in Southern California.

Her family announced the death in a statement on Facebook, noting that she “has been a symbol of triumphs and hope for over 30 years sharing her journey with breast cancer.” Additional details were not immediately available, but for many years she owned a 12-acre estate on the Santa Ynez River near Santa Barbara.
