Chorus  Am – G – F – Em

During the verses, there is a riff that is played between the G-Bm, and the Bm-F 
chords.  Listen to the song, and you will hear what I am talking about.  That riff is tabbed here.

Riff:
E|-------------------|
B|-------3h5--3------|
G|-----------------4-|
D|-------------------|
A|-------------------|
E|-------------------|

G – Bm – F – Em (x2)

VERSE 1
G   (Riff)         Bm  (Riff)          F         Em
     You let me         inside your brain
G   (Riff)            Bm   (Riff)        F          Em
      Contagious            again and again

Well I've noticed along the way
That it's beautiful and I'd love to stay

CHORUS 1
Am                          G                                   F             Em
     Won't you come down and sleep on the ground
Am                          G                                    F            Em
     And I'll be your friend and I'll take your hand

VERSE 2
All my fault, I said something wrong
And I hurt you, I went overboard
So forget it, please forget it
'Cause I do care, I just lost my head

(CHORUS 1)

BRIDGE (G – Bm – F – Em, same as verses, just no riff)
I used to play on the green
Then I saw what I had never seen

(CHORUS 1)

CHORUS 2
See it in me, the branch of a tree
Under this wing, secrecy sings

VERSE 3
What can I say to make you smile
It's been an hour, it's been a while
So believe me, please believe me
'Cause you know your the girl of my dreams
