“The Choral Sea was a complete experiment. We set up with am 808 drum box to get a click track. I followed the method that Mike Chapman had used [for Blondie’s ‘Heart Of Glass’.] We recorded the bass drum first, all the way through the song, punching in and out making sure it was perfectly in time. Then we did the snare drum, then the hi hat, then the top kit. So everything was perfectly in time, clear, clean and punchy sounding.

We started to building this song up as an instrumental. We had the rhythm, but we didn’t really have a concept and started to stumble with where it was going to go. So we took a break for dinner and I turned on the TV in the control room and Jacques Cousteau came on. One of these incredible underwater photography programmes of his. It suddenly occurred to me - let’s do this like a soundtrack to an underwater show.

We made up a basic story where certain events were going to happen. These fish were going to come this way, this shoal of fish this way, an octopus would come over here... so we had all these ideas mapped out like a mini movie.”

“Prior to that, it was called ‘Spunky Sheila’.”
