'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.

For me I have learned to enjoy everything, especially performing live, so much more. I used to get horrible stage fright when I was younger and today and just love to sing for anyone who still turns up at my shows!

I simply have a marvellous life, a very lucky life.

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.

The "Great Walk to Beijing" was a fundraiser for my cancer center. It was a three-week trek with fellow cancer "thrivers," including celebrities ranging from Joan Rivers to Leeza Gibbons, and Olympians.

I love animals. They give so much to you and demand so little. And you can trust them.

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.
