"And I had this feeling of complete triumph, of victory. I’ve always wanted to write a song that people would dance to.
"I’ve done songs that people have sat and listened to, and reflected on the thoughts it produced in them; or songs people would cry to when they were going through a break-up. "But to do a song where people’s first instinct is to dance, oh, I’ve wanted that for so long."
