I look at my hands and go, 'Hmm...what happened? Whose hands are those? Oh my God, they're mine'

Being diagnosed with cancer really opened my eyes to the fact anyone can have it and that even though we think we have control over everything in our lives, we don't.

It wasn't until I moved to Nashville that I realized what an amazing community it is. It's the thing I've been missing my whole career, the feeling of being able to sit around with a guitar and have people know each other's songs and know songs from people who've influenced all of us. When I moved here pretty early on Vince Gill started calling me to do guitar pulls, and I thought, gosh, this is just like heaven on earth down here.

Then when I cut my hair short, my career tanked for about four years!

I want to collaborate with Amy [Winehouse] because she's really hot and cool right now. I know one song Rehab was very popular particularly because a lot of young people are in rehab as well. In fact I'm thinking about going. It looks like loads of fun and I know my career will benefit from it.

More than 10 million Americans are living with cancer, and they demonstrate the ever-increasing possibility of living beyond cancer.

I'm not much of a partier anymore. I enjoy clarity much more.
