I've been in bands since I was about fifteen, so there are probably quite a lot of terrible teenage songs kicking about somewhere. I'm not sure what it was about to be honest, I think it was probably just something along the lines of teen angst.

Everyone's [ me, Iain Cook and Martin Doherty] equally involved in all the writing. Normally we'll start with a sample or a drumbeat, or a synth sound or something like that, and that will spark the initial idea. And then we'll write an instrumental sketch of a song, and then we put on a nonsense vocal melody, which is always my favourite bit because it obviously sounds amazing.

Nobody is strong 100 percent of the time, or falling apart 100 percent of the time; sometimes you're doing both at once.

I try not to say exactly what songs are about sometimes, because I feel like it ruins it for people.

No matter how many people try, no matter how many fancy songwriters in Los Angeles try to break it down to a formula... to an extent, there isn't a science to writing great songs, I suppose.

I don't know Justin Bieber so I wouldn't want to marry a man I don't know.

I quite like being removed from the industry stuff so that when we're not on tour and we're writing, we're in a small room and you can't get out physically. I like that mental checking-out aspect - I think it's quite nice.
