This song is half step down but if your voice is high enough you can pull it off in stardard.

VERSE:
       Am
And he set me on fire I am burning alive
         F
With his breathe in my lungs I am coming undone

PRECHORUS:
Em                   Am       G       F
And I cannot hold it in and remain composed
Em               Am        G     F
Loves taken over me and so I propose
F                                         C
The letting myself go I am letting myself go

The pause...then BAM
Slide from a C power chord down to F

Chorus:
F                                                           C    C/B
You are my joy, you are my joy, you are my joy, you are my joy
(repeat twice)

Turn:
          F
I need to catch my breathe, I need to,
            F                          C
I need to catch my breathe give me a moment... now

Bridge:

Violin tabbed for guitar. I think it sounds good using a slide and a touch of  delay. 
with it however you want.

OUT:
         F
And I'm laughing so hard
         F
And I'm laughing so hard
         F
And I'm laughing so hard


There you go pals.
