Then, in 1978, we got this producer, Mike Chapman, who asked us to play all the songs we had. At the end, he said: "Have you got anything else?" We sheepishly said: "Well, there is this old one." He liked it – he thought it was very pretty and started to pull it into focus. The boys in the band had got their hands on a new toy: this little Roland drum machine. One day, we were fiddling around with it and Chapman said: "That's a great sound." So we used it.
If you listen to the early versions of Once I Had A Love aka The Disco Song it's quite a transformation.
I love how bands have classic songs on their hands by accident.
