It was just something that I'd wanted to do for a long while actually. It wasn't something that I'd given much thought to in the previous albums but I just felt that when it came to the fourth album… “Oh well, I'm going to do it.” And it needed a lot of thought. I did a bit of research, y'know, but I still wanted it to be very much a Queen thing. I wasn't trying to say that it was the authentic opera or whatever, I just wanted it to be opera in the rock ‘n' roll sense.
