I wouldn't really say anything was an accident, but I do remember spending quite a lot of time working on the chords for Radio Ga Ga, which are quite involved. I remember thinking, “That's a good chord sequence.” It took me a while to work it out again when I'd forgotten it. I'd say that's the closest thing to something like that. Radio Ga Ga was really more chordal than I'd been up ‘til then. I just wanted to be rhythmic and melodic.
