“If you look at the Billboard charts, Eye In The Sky could be our biggest hit. Certainly in terms of exposure through the intro, which is called Sirius, it’s become a sports anthem, particularly with the Chicago Bulls and the New Orleans Saints.

“I wrote the bulk of Sirius, and Eric [Woolfson] wrote the bulk of Eye In The Sky. He’s no longer here to tell us of his lyrical points, but I think the song is a vague reference to an Orwellian 1984 situation – hidden cameras, surveillance. The idea is that no one is alone; somebody’s always watching you.

“I think this was the first album on which I used the Fairlight. It was a revolutionary instrument, the forerunner of all technologies that became known as ‘sampling.’ You could actually record a sound onto a computer and then play that sound on a keyboard. It really was revolutionary at the time, but people would laugh at it now. It had a learning curve. You couldn’t just plug it in and play – you had to read the manual. But I’m an engineer, so I like stuff like that.”
