On Wednesday, on the Today Show with Hoda Kotb, singing diva Olivia Newton-John emotionally bonded with Hoda Kotb when she came to know that she was also a cancer survivor. The 75-year old entertainer is still very popular for Grease as well as for the track–Physical, which recently celebrated its fortieth anniversary.

The veteran actor and singer opened up about her long battle with cancer. She also empathized with her interviewer’s battle with cancer. When Kotb thanked her for her kind words, Newton-John said that they were “sisters” and that cancer was “unknown destinations and surprises and turns.”

She also said that she was a “lucky” person as she is bravely facing her current battle with cancer. The “Hopelessly Devoted to You” singer said that she had her “days” and her “pains” but the cannabis that her husband grew for her had been a “huge part” of her healing.

Olivia Newton-John has had a long journey with cancer. The “Twist of Fate” singer was first diagnosed with cancer in 1992 and then again in 2013. Once again, in 2017, she faced another round with cancer that had spread across her body

She was astounded at the success of her hit 1981 track Physical as it’s four decades since the track was released. At that time, the song was considered racy and she had a few qualms when it was released.

She wondered how it was possible that people still liked it and compared its lyrics to a lullaby considered the lyrics of recent tracks. She had told her manager that perhaps she had gone too far but he had said that it was too late to go back and that it had “taken off everywhere.”

Olivia had made a virtual appearance on Dancing with the Stars for Grease Night. As the contestants performed, she shared personal details on the inspiration behind the songs on Grease.
