We met at my studio in London. She had the bare bones of “Clean.” She had the lyric, the chorus and the chords. I thought it was brilliant. I was really writing the tiniest amount just to help her do what she does. I put some noises to [“Clean”], played various instruments on it, including drums, and anytime she expressed she liked something I was doing, I did it more. It was a really fun day. She recorded all her vocals [for “Clean”] during that one session. She did two takes, and the second take was it. We always thought she would probably re-record it, because we thought it can’t possibly be that easy. But after we lived with it for a few months, we felt it was great. I knew she loved [“Clean”]. She said she loved it and her mum loved it. But I wasn’t sure it would be included on the album. But everyone felt it had something special. It came together really magically.
