There's a lot to say about Killer Queen. It was made at a time that I was almost dying of stomach problems, I was in the hospital in the middle of the recording that album, during which time, although we'd recorded together the beginnings of Killer Queen, the boys went in and did some harmonies and I remember they brought it in for me to hear in hospital and I went, “it's really good but it sounds very abrasive, you know, perhaps we make it sound more rounded in the vocal harmony department.” So Freddie said, “you're absolutely right, Brian, and we will do it again when you get better so you better damn well get better.”
