I live every day to its fullest extent and I don't sweat the small stuff.

I don't have the desire that I think a lot of performers feel - to get the applause. It's not life or death for me. I love it and it's exciting, but it's not something I crave or miss, so I don't need to perform; I don't have that desire. I like to sing, and I love doing what I'm doing, but it's not a dire need.

A few years ago I appeared on GLEE and, Jane Lynch and I did a remake of the song that was very popular - someone told me it was in the Top 100 when it was released. First, walking on the set of GLEE the day we filmed it was surreal as they had recreated the entire original set from the music video. It was bizarre - but fun.

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 live my life in gratitude.

As for the industry, it has certainly changed. I think with all of these television shows and YouTube and the internet, you have so much less time to develop as an artist and perfect your craft. So many things today are "instant" and, that's not always a good thing.

There's a kind of a line between music and math, so I guess I got the music gene, thank goodness. But my mother wasn't too thrilled. She wanted me to go to university and get a degree or do something, and my father, he liked opera so he wasn't too thrilled either, because he wanted me to be an opera singer and I didn't have - as he said, I don't really have the strength to do that.
