This is a lovely track of Nerina's, originally intended for Year of the Wolf. I'm a 
little unsure of some of the lyrics, but the tab's more or less spot on, I think.

The intro goes like this:

Am (x02210@1)                               GOh (320003@1)what webs we weave, what little things begin.
        Am (x02210@1)           GAn (320003@1)epic fortune, or disaster.
Oh, how could you know how it would all unfold?
In those seconds in between. Your smile and your laughter.

So you had a little boy then you had a little girl
You bought a bigger house; you were happy with your world
But one day you woke up, and you had a question

Now no matter what you do and no matter what you know
You cannot fill that hole, you cannot fill the hole
    C (x32010@1)                     DYou (xx0232@1)carry on, cos everyone carries on

Cmaj7 (x32000@1)       D6I'm (xx04xx@1)so happy, you're so happy
Bm7 (x20202@1)          Cmaj7Oh (x32000@1)my God, I'm crying
I do my best each day to keep my head up and keep smiling
I'm so happy, you're so happy
We're so good at lying
I'm so happy, you're so happy now.

Now you pass through life and make it meaningful
Try to make it all make sense
And know what it's for
Do you buy a book or two and learn them off by heart?
And then wander aimless through the halls and corridors?

So I'll have a little boy, if I cannot have a girl
I'll buy a bigger house and I'll try to save the world
I'll carry on, maybe I'll just try to carry on

I'm so happy, you're so happy
Oh my God, I'm crying
I do my best each day to keep my head up and keep smiling
I'm so happy, you're so happy
We're so good at lying
I'm so happy, you're so happy now.

[Here, I'd recommend playing just these bass notes. She plays C-B-F#-G two octaves up at 
the same speed over the top, but it just gets over-complicated, I think. You'd have to 
play the whole thing up near tenth fret, and this sounds better, on balance.]

C (x32010@1)  D (xx0232@1)   F# (244322@1) GCos (320003@1)love comes swiftly, when you least expect it
But so does sorrow, when you least expect it
Oh, love comes swiftly, when you least expect it
But so does sorrow, when you least expect it

(To chorus chords)

Oh, I'm happy now...

I'm so happy, you're so happy
We're so good at lying
I'm so happy, you're so happy now.
I'm so happy, you're so happy now.
Cmaj7 (x32000@1)       D6 (xx04xx@1)            GI'm (320003@1)so happy, you're so happy now.
