Olivia Newton-John was a four-time Grammy Award winner whose music career included five number-one hits and another ten top-ten hits on the Billboard Hot 100. She also starred in the musical film Grease including two major hit duets with co-star John Travolta: "You're the One That I Want" and "Summer Nights". When I was a kid, it seemed "Physical" was everywhere, because it was.
