But if this ever-changing world in which we live in
Makes you give in and cry
Say live and let die
This lyric never used to bother me until my wife pointed out that it's ungrammatical. She'd accept either "world which we live in" or "world in which we live", but repeating the "in" is just plain wrong. I countered that maybe the real lyric is "world in which we're living" - it's not, but hey, it fits - but my wife said she'd hate that, too, because it would be lousy enunciating.
So unfortunately it now bothers me as well every time I hear it. Though it's still the best Bond theme. Even better than the title theme to "Octopussy".
(Disclaimer: There is no title theme to "Octopussy". But there should be.)
(Disclaimer: Do not take Paul McCartney's advice. Dissatisfaction with a society in flux is an acceptable excuse to kill people only if you're James Bond.)
