Okay, so I knew this song previously, took a look at the online version here, and I 
to post my own, with some minor changes, as well as the lead in in the slower, ballad 
of the song.

Tuning standard Eadgbe
The Intro is pretty simple. There are some notes embellishing it at some live 
but this works for me.
|------------------------|
|------------------------|
|----0-----0-----0-------|
|--3-----3-----3---------|
|------3-----3-----3-3---|
|----------------------3-|

Alternately, you can play with more chord values
  F   C       C G
|-------|X3 |-----|
|-1-1-1-|   |-1-1-|
|-2-0-0-|   |-0-0-|
|-3-3-2-|   |-2-0-|
|-3-3-3-|   |-3-2-|
|-------|   |---3-|

Which pretty much covers that.

The song itself goes through the following chords.

F (x3321x)
C (x3201x)
Gsus4 (330013)
G (32003x)
Am (x0221x)
F              C
When you're in love
           F           C
There's no time and no space
              F         C
And there's a permanent smile
        Gsus4 G
On your face
         F           C
And your friends all complain
            F     C
That you're going insane
        F
But the truth is
C            Gsus4  G
They're just afraid
~~~~~~Chorus~~~~~~~~~~~~~~~~~~~~
(and I said)
Am   G    F       C
Hey, Hey, Hey somewhere
F                          C         G
You threw your fear in the Sea of No Cares
      Am   G    F       C
(and) Hey, Hey, Hey somewhere,
F                           C         Gsus4 G
 You threw your fear in the Sea of No Cares
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(Then repeat intro for filler)

When you decide
That what counts is inside
Your friends all say
It's a lie

And there's no brighter light
Than the look in her eyes
Than when you're walking her home
Through the night

(Chorus)

(follows the bridge, listen to the song for rythem.)

Let yourself go with the tide
There's an angle by your side
to ni-i-ight.

(Intro pattern once)

Oh, Back at the bar
getting cynically stoned
Your friends
Are drinking alone

But it's funny
'Cause they dont' even Cross your mind
When she asks you in,
to her home

(Chorus X2)

And that's it. Just repeat the chord progression with the rythm in the words, and enjoy.
