David was living in Switzerland, where we were recording in a studio we owned at the time in Montreux. He basically just popped in to see us. Freddie had met him before. We all had a little chart and then went straight in the studio and started playing around. We played a few old songs and then something new started to happen and we said, “Okay, let's try and record this.” It was a truly spontaneous thing. We felt our way through a backing track all together as an ensemble. And then David brought up an unusual idea for creating the vocal. He was kind of famous for writing lyrics by collecting different bits of paper with quotes on them. And we did a corresponding thing as regards writing the top line for the song. When the backing track was done, David said, “Okay, let's each of us go in the vocal booth and sing how we think the melody should go - just off the tops of our heads - and we'll compile a vocal out of that.” And that's what we did. Some of the original bits even made it onto the record. Freddie going “b-b-b-boom-ba,” that scat singing stuff, was part of the initial track he went in and did off the top of his head. Odd, isn't it? That's why the words are so curious - some of them, anyway. There was a point where somebody had to take control, and I think it's fair to say that David took the reins and decided that he wanted to rationalize the lyrics and them say what he felt they should say.
