You can add up the parts →[More:]

but you won't have the sum

You can strike up the march,

there is no drum

Every heart, every heart

to love will come

but like a refugee.

(From Leonard Cohen, I'm Your Man. . .the movie. Julie Christiansen and Perla Batalla spend the whole concert/movie singing backup, and towards the end, get to sing this song. For me, the highlight. They end up hand in hand, arm in arm, and it seems very genuine. They both sang backup for Cohen for years. You should rent the movie. . .not for the film making for for the music.)
