Now, Great Northern is a little tricky to tab because a lot of the chords are actually 
chords, but here's my stab at it.

The untabbed parts are not guitar chords, they're synth, but here are the chords anyway: 
C#m Cm F Bm

Watch out cause we're trouble shooting

On the weekend

We try to connect but don't hold your breath

Cause we can
F          Am
Love you a little
         F
Gets you through
       Am
To the middle

It's a sound that you learn to hate

We try to get to you but don't be late

Cause we'll...
F          Am
Love you a little
         F
Gets you through
       Am
To the middle

C F C F
C F C F E

1-2-3 is how you get to sleep

But don't forget your mother

While you count your sheep

Cause she'll
F          Am
Love you a little
         F
Gets you through
       A
To the middle

Pick'n up the pieces from the night

Into the day is how we
F          Am
Love you a little
         F
Gets you through
       Am
To the middle

If the summer will be easier

To finally let me go

F          Am
Love you a little
         F
Gets you through
       Am
To the middle
F          Am
Love you a little
         F
Gets you through
       Am
To the middle

C F C F
C F C F E

       C               F
Didn't mean to let you down
     C                  F
Just thought you'd hang around
    C                       D       F Dm
But we've been waiting for so long [x4]

Outro:
F G F Am variation (play with it a little! Most of the outro is Rachael's 
but mimic it with a guitat or just make it up.)
