It was evolved in an unusual way, which David really brought to the table, wherein we worked on the backing track together, and we sort of, felt our way through it. But once we had a backing track which we liked, David's idea was to get everybody to go into the vocal booth and just sing the first thing that came into their heads. And what would then happen would be, we would compile it and see if it suggested the way the song should go, and some of those takes from Freddie survived to the final vocal, strangely enough, including this bit, I think, and the sort of, ad-libbing bits. But then, it was David who really got up a couple of days later and decided what the song should be about. So the song kind of, does sound like a jigsaw puzzle, but I think it works amazingly well. Some great hooks. It's one of the songs which doesn't seem to date as well I must say. It always has something to say.
