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.

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.

I think Westlife is very unique: we have a certain sound; we do our thing our way, and we don't try to change too much. I think that's what the fans love about us. We keep giving the fans what they want every year. The style of music never really changes too much.

My mum and dad ran a family cafe in Sligo for 35 years and worked long hours. We grew up in a very hard-working family and had a lovely atmosphere, as we lived above the restaurant. It definitely made me want to work hard, whatever I chose to do. As the baby of seven kids, I was definitely a bit spoilt.

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.

When your child is looking up at you and you are putting them to bed at night, and they are just lying there, you have to remind yourself that's what it's all about.
