My father is doing a radio program - classical music. He has a beautiful speaking voice and that's his passion in life, his music. My mother lives in Melbourne and is an avid photographer. She's also started writing for a magazine out there and she submits poems, very funny ones, and articles. In some way or other, my family is always doing something with the media.

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.

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 look at my cancer journey as a gift: It made me slow down and realisethe important things in life and taught me to not sweat the small stuff.

I have really been blessed in my career with some wonderful songwriters and in turn, songs.

Nothing I have done professionally will top the feeling I got when singing with John Farnham at the 2000 Olympic Games in Sydney.

Nature is the most beautiful thing we have. It's better than art because it's from the creator.
