Exactly as he plays it in this awesome live performance from BBC 4's 'Songwriter's 
Circle' (http://www.youtube.com/watch?v=stjaM9MXQNY)
Standard tuning, capo 5th.

INTRO RIFF
The intro is a nice Am | G add4 | C | G add4 progression. He plays it with this little 
fill in place of the last chord though:


So, start with:

[INTRO RIFF x3]

VERSE 1

         G          D
From the top of the bus

    Em                          C
She thought she saw him wave

          G             D
She's all Tuesdays, and forgetfulness,

      Em           C
And a little money saved

BRIDGE 1

         Am            D
Does she know? I don't know.

         C           D
But from here, I can tell

CHORUS

         G  D           Am         C  D
It would try the patience of angels

         G  D           Am         C
It would try the patience of angels

[INTRO RIFF x 1]

VERSE 2

        G                D
And you know something's wrong

         Em                 C
When the morning hurts your eyes

        G               D
And the baby won't stop crying

          Em               C
You'll be waiting 'til you die

BRIDGE 2

        Am     D
Would I be any good?

     C            D
If I was, would I find...

[CHORUS]

VERSE 3

          G          D
There's a door, in a wall

     Em          C
In a house, in a street

     G          D
In a town where no-one

          Em   C
Knows her name

(She's the patience of angels)

[INTRO RIFF x1]

[BRIDGE 1 x1]

VERSE 3 OUTRO VAR

          G          Dadd4
There's a door, in a wall

     Em7         Cadd9
In a house, in a street

     G          Dadd4
In a town where no-one

          Em7  Cadd9
Knows her name

[VERSE 3 OUTRO VAR x1]

(She's the patience of angels)

[INTRO RIFF x2]

[CHORUS]
