歌詞: Siobhan Donaghy. XY.

In the descent of man
Heading for extinction
Catch this if you can
I make this prediction

You're my XY chromosome
And the love between us
Is fully blown
That's why here at home
I'm you're one and only
XX alone

Gone for all humanity
A Shakespearean tragedy

We're all XY, XX chromosome
And the love between us
Is very nearly blown
And that's why we are all at home
Feeling lonely
XY, XX alone
XX alone

God will all humanity
Fail to find a remedy
We haven't found a place where we
Can all human kind together be

We're all XY, XX chromosome
And the love between us
Should be fully grown
And that's why
We should be all at home
And never lonely
XY, XX all one

Mmm, ah, ha
Mmm, ah, ha
Mmm, ah, ha
Mmm, ah, ha

I'm dreaming
The meaning of words
And, what do they all mean
It's all so absurd
Mmm

We focus
(Yeah)
On all the worst things
And we're all full of fear
For what the life brings

You're my XY chromosome
And the love between us
Is fully blown
That's why here at home
I'm you're one and only
Xx alone

We're all XY, XX chromosome
And the love between us
Should be fully grown
And that's why
We should be all at home
And never lonely
XY, XX all one

Mmm ah ha
Mmm ah ha
Mmm ah ha
Mmm ah ha

XY, XX all one
XY, XX all one
XY, XX all one
XY, XX all one
XY, XX, XY, XX
XY, XX all one
