Queen's 'Seven Seas of Rhye' was originally entitled 'Seven Seas' - much snappier, one would think. Anyway, those vitamin supplement people threatened litigation, Freddie went all huffy and re-named the track just to keep people guessing.
Freddie's earliest idea for the title was, in fact, "Christians can corrupt childrens' CD's, creating chaos", which was then shortened to "7 C's". This proves the monkeys and typewriters theory of probability.
