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.

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 am very glad there are quite a number of people born with a gift and a liking for all of this; like great chessplayers who play sixteen games at once blindfold and die quite soon of epilepsy. Serve them right! I hope the Mathematicians, however, are well rewarded. I promise never to blackleg their profession nor take the bread out of their mouths.

Some people are just born stars - you either have it or you haven't, and I was definitely born one.

Find out what your gift is and nurture it.

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.
