You're the One That I Want by John Travolta and Olivia Newton-John

About

The fourth track on the Grease Original Soundtrack made for the 1978 film adaptation of the 1971 musical, performed by John Travolta and Olivia Newton-John as their characters. “You’re The One That I Want” is played near the end of the film, just after Sandy showed up at the carnival with a new makeover and attitude that managed to get Danny to notice her and not feel ashamed of being with her. It was one of the best-selling singles of all time, having sold over 6 million copies among the United States, the United Kingdom, Germany and France alone, and reaching #1 on many charts.
