Acting is a difficult profession, it really is. It's different than singing. With singing you may have one song and four people to record it - but they'll all do it differently and they'll all have that option. Whereas with actors there might be one part, and five hundred actors all want the same role - it's so much more competitive. It's an incredibly painful profession because you get so much rejection.

A lot of songs are inspiration and help people through pain, grief and loss.

Cancer got me over unimportant fears, like getting old.

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.

The only weights I lift are my dogs.

Man is taking over the forests and polluting the oceans, the animal species are threatened. I try to contribute as much as I can. We're really messing up our environment. I try to get people more aware of what's going on so that they can, even in a local way, try to prevent pollution to their lakes and rivers and prevent nuclear dumping in the oceans - it's bad enough that they're doing it in residential areas, but putting it in the ocean! Eventually it's going to pollute our food resources and, if the ocean dies, we're gone.

I live my life in gratitude.
