“For the longest time, we just had the opening figure and some other parts. The way that it’s broken into three sections wasn’t the original intention. It was meant to be a long song, but we were like, ‘This is going nowhere.’ So the arrangement that is there came together the day we recorded it. I just winged it. We felt strongly about it, and that was it.

“If you take those changes, Section Two and Section Three, and played them over the opening beat, they would feel kind of unremarkable. It was something about placing them in a different context a la Yes, with a little nod at the end to Vangelis [laughs], and it just seemed to work. We didn’t sit around and intellectualize it. There it is – it works.

“What’s really interesting is, when we went to play the song live – you think, OK, it’s this one thing that’s on the record – it became a total show piece.

“The soloing... I think that’s a Strat. I know I hooked up two phaser pedals back-to-back, and they were exploding on each other. As long as I kept playing, it worked, but if I stopped it made this horrible death noise.”
