When I was writing the song, I thought that these people have entire lives in there. They're not writers, but they all have stories to tell. Some are very, very down deeper than others.

Because of my song 'Sam Stone,' a lot of people thought I was interested in writing protest songs. Writing protest songs always struck me as patting yourself on the back.

I used to write random little stupid things when I was five, but then the first song I really wrote was one called 'Fingers Crossed,' which is on SoundCloud.

When I was four, I wrote a song about falling into a black hole.

A song is like a dream, and you have to make it come true. They're like strange countries that you have to enter. You can write a song anywhere, in a railroad compartment, on a boat, on horseback -- it helps to be moving. Sometimes people who have the greatest talent for writing songs never write any because they are not moving.

I wanted a participation song, something the fans could latch on to. It was aimed at the masses. I wanted to write something that everyone could sing along to, like a football chant. And at the same time, I thought it would be nice to have a winning song that's meant for everybody. It worked a treat.
