The year of 1978, was a memorable one for "Grease". A few decades later, Olivia Newton John sings with John Travolta the powerful song that made the musical called "Grease" and 1978 so memorable. "You're the One That I Want" in 1978, was electrifying, with the beautiful and breath-taking Olivia Newton-John singing with the heart-throb from "Welcome Back, Kotter".
The video below, of the originally sung "You are the One That I Want" in 1978, shows the entertainers in their prime. The above video, shows that the dynamic chemistry of Olivia and John is still "electrifying"...
(Olivia, certainly looks good in black; as well, as John.)
