In 1978, Newton-John starred in the musical film Grease, which was the highest-grossing musical film at the time and whose soundtrack remains one of the world's best-selling albums. It features two major hit duets with co-star John Travolta: "You're the One That I Want"—which is one of the best-selling singles of all time—and "Summer Nights". Her signature solo recordings include the Record of the Year Grammy winner "I Honestly Love You" (1974) and "Physical" (1981)—Billboard's highest-ranking Hot 100 single of the 1980s. Other defining hit singles include "If Not for You" and "Banks of the Ohio" (both 1971), "Let Me Be There" (1973), "If You Love Me (Let Me Know)" (1974), "Have You Never Been Mellow" (1975), "Sam" (1977), "Hopelessly Devoted to You" (1978; also from Grease), "A Little More Love" (1978), "Twist of Fate" (1983) and, from the 1980 film Xanadu, "Magic" and "Xanadu" (with the Electric Light Orchestra).

With global sales of more than 100 million records, Newton-John established herself as one of the best-selling music artists of all time, as well as one of the highest-selling female Australian artists.
