Verses   G - Bm - F - Em
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.

G - Bm - F - Em (2x)
VERSE 1
G (320003@1) (Riff)         Bm (x24432@1)(Riff)          F (133211@1)       Em (022000@1)    You let me         inside your brain
G (320003@1) (Riff)            Bm (x24432@1) (Riff)        F (133211@1)        Em (022000@1)     Contagious            again and again

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

CHORUS 1
Am (x02210@1)                        G (320003@1)                                 F (133211@1)           Em (022000@1)    Won't you come down and sleep on the ground
Am (x02210@1)                        G (320003@1)                                  F (133211@1)          Em (022000@1)    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
