So I took my AD's and decided to make a better version of these chords.
Loosely based of the tab by 'housemartin' so some credit to him.

Its rather easy to play if you've got your barre chords and fast changes down.
I believe this to be almost perfect but, as always, refer to the actual song to 
fine tune your rhythm/strumming.
Enjoy!

                             Ab         Eb
Meet me in the middle of the morning        
                   Bb             Cm
When the crows fly highest in the sky

          Ab              Eb
Oh, but I never found you
              Bb              Cm
No matter how hard I tried to
         Ab              Eb 
Oh no, I never found you
         Bb       Cm
Sarah if only you knew 



    Ab  Eb              Bb           Cm
Serotonin,    burning a hole into my heart
                Ab     Eb
Felt like I was floating

But now I'm coming down with you so
Cm                 Ab    Eb    Bb    Cm   (Repeat main chord sequence)

Meet me at the bottom of the ocean
                 Bb           Cm
Feel its fingers tickling our skin

you mix your  magic potion
                 Bb                     Cm
The old familiar feeling starts to kick in
             Ab                 Eb
But now it's fading and I can't hear what you're saying
   Bb                       Cm

It's fading and I can't hear what you're saying
   Bb                       Cm
It feels like it's slipping


             Ab  Eb           Bb           Cm
It's the serotonin, burning a hole into my heart
                Ab   Eb                  Bb           Cm
Felt like I was frozen, yeah but now I'm coming up so hard
    Ab  Eb                    Bb         Cm
Serotonin, well you're really tearing me apart
                Ab   Eb                  Bb            Ab
Felt like I was frozen, yeah but now I'm coming out so hard
