I grew up in a very small, rural country town, and we didn't really have 'the arts.'

Three-quarters of my family is Irish. Of course, the "Kazee" is not.

I never really trained to be a musician, but I've been playing guitar since I was around, like, 13 years old. For me, the guitar has always been the instrument that I've played. I play a little piano. I taught myself everything by ear. I don't read music at all, which has not really been a hindrance.

My mother always told me before shows to stand up and show them whose little boy you are.

For me, music is sort of my passion, more so than being an actor. I just never tried to make a career as a musician. It was just something that I did on my own time, just for me. I had written a lot of songs, but I don't really record a lot of music because, for me, it's the same way as a poet: I write to get things out. It's sort of cathartic.

The thing is that I'm an actor first, and in 'Once,' I was able to be a musician and a singer as well as an actor.

When you start hiding things away, that’s when the darkness creeps up. Sunlight is the best disinfectant.
