Lyrics:

Add it up, add it up, add it up

There's no more little secrets we haven't yet disclosed
We bore the living daylights off anyone too close (Anyone too close)
And all our cards at Christmas are written to us both
Count them up, who's got the most?

Said we'd be close, said we'd work perfectly
Said that we'd toast beautiful company

Closer than a sister to her baby brother
Closer than a secret agent working undercover
It's too close for another, it's too close for a lover
We are each other, we are each other

We've been through all positions and this one's definitely best
You move Middle East and I'll move Wild West
What happened to our friendship we could easily have guessed
Add it up, we're self-possessed

Said we'd be true, said we'd be so, so proud
Just me and you, we'd shout it out aloud

Closer than a sister to her baby brother
Closer than a secret agent working undercover
It's too close for another, it's too close for a lover
We are each other, we are each other

Add it up, add it up

Remember we went shopping and we went by piggyback
I shaved all my legs and you grew hairs upon your back
Well no-one's ever been since to this lover's shack
It's a cul-de-sac

Said we'd be close, said we'd work perfectly
Said that we'd toast beautiful company

Said we'd be true, said we'd be so, so proud
Just me and you, we'd shout it out aloud

Closer than a sister to her baby brother
Closer than a secret agent working undercover
It's too close for another, it's too close for a lover
We are each other, we are each other

We are each other, we are each other
