Once this basic structure was sorted out, Freddie would begin the whole process of assembling all the other necessary components to achieve the song. No overall vision of how the song would ultimately sound ever arose before the very basic skeleton had been assembled. So often, the end result would bear little resemblance to the original concept. A prime example of this was Radio Ga Ga which sounded to me when Roger played his initial tape more like the Ave Maria from Verdi's Otello – but that's to come. Incidentally, titles of tracks often changed between conception and fledging. Radio Ga Ga on one of the original cassette boxes is called Radio Ca Ca.
