John [Travolta] and I have remained very close friends ever since we did Grease. When I was told that "You're the One That I Want" was named the #1 duet in history and, during a text chat with John letting him know he said "we should record a Christmas song." Of course I said yes.
I love seeing young girls and their parents and grandparents at my concerts all loving the music from Grease when I perform those songs (and yes, I do perform a bunch of them!).
As for highlights, of course "Grease" changed my life and I will always be grateful for that experience.
'Grease' changed my life in the most amazing way, and I've had such an amazing life. When things go wrong, you've got to believe you will get through them and focus on the positive things in your life.
