It's a big deal to bring your family on the road, you know? I'd love to do it sometime, but you have to work out schools and all that.

If I'm honest, I thought Westlife would keep going for longer than it did - we all did - but it sort of came to a natural end. When we decided we were going to split, I thought, 'If I'm going to sing, I'm going to have to do it solo.' Also, financially I was broke, so the decision was ultimately made for me.

You've got to go down the road you naturally go down, and for me it was pop, folk country, just feel-good music. I suppose most of my songs are very up-tempo.

Why me? Why did this happen? How could I be in Westlife and then have nothing to show for it financially at the end of it? But it's like, why not me? That's just life. It's tough. There's a lot more problems in the world. There are a lot of people who would wish to God they had my problem instead of having a sick child.

My wife is my best friend. The thought that people are afraid to go home to their partners for fear of being abused physically or emotionally makes me feel sick. It's not easy but you need to get help and get out.

I think that lyrically, 'Safe' is a very positive song: it's very strong; it's about keeping somebody safe and protecting people. I think everybody anywhere in the world can relate to it. I think everybody wants to feel safe; everybody wants to feel protected.

When you realise that money doesn't actually make you happy, it's a quick fix to have things you've always wanted, but then when you have it, you realise that's not what actually makes you happy. It's more about having a great marriage and happy children; that's what life's all about.
