The first time I heard Freddie playing that song, I was lying in my room in Rockfield [a residential recording studio in Wales], feeling very sick. After Queen's first American tour I had hepatitis, and then I had very bad stomach problems and I had to be operated on. So I remember Just lying there, hearing Freddie play this really great song and feeling sad, because I thought, 'I can't even get out of bed to participate in this. Maybe the group will have to go on without me.' No one could figure out what was wrong with me. But then I did go into the hospital and I got fixed up, thank God. And when I came out again, we were able to fin- ish off 'Killer Queen.' They left some space for me and I did the solo. I had strong feelings about one of the harmony bits in the chorus, so we had another go at that too.
