Angus has had a few swings at me, maybe two or three times in our whole career. But then it's done, and it's not gonna drag on, because it's not worth it. We have to stick together. And we know that.

People paid money for tickets to see us and be entertained by us, and we've never forgotten that. Anything after that was a bonus.

I was more of a melodic player. Angus was more into the rock world. Straightaway, I said this is how we should do it. It was never a brotherly squabble but the opposite, because we just wanted to do good as a band.

I've never felt like a pop star - this is a nine-to-five sort of gig. It comes from working in the factories, that world. You don't forget it.

I got into a lot of trouble. Maybe that's why my parents didn't really like me and I didn't blend in with my family. I was always the naughty one.

There are lots of reasons for that gap between men's and women's wages but to me, the big one is the work-family issue. Trying to juggle children and a job is tough under any circumstances, but especially if you're shooting for the kind of career that involves long hours at work and being on call 24-7.

I'm really focused on my research almost 100 percent. That, and my family and kids.

Everything in my life boils down to my mother. A tradition, which a lot of people do not know of, is that while I'd give my father the money I earned, anything that was special to me - like an award or an album - would be given to my mother.
