So, I was looking for the chords for this song on UG, and didn't find a good
chart...sad day. Its super easy, though, so here's my shot at it.

The official video on YouTube shows him playing it at CAPO 2, so that's where
my chart is. The time signature is 3/4.

Fun chord of this song:
Esus2
e|-0-
b|-0-
g|-1-
d|-2-
a|-0-
E|-2-

Here's my best shot at the strum pattern, too:
E          Esus2     E          Esus2
D--D-U--U-|D--D--D--|D--D-U--U-|D--D--D

Also, putting the emphasis of your strums on the bass (deeper) notes on each
Esus2 chord makes it sound nice. Specifically, on the three down-strums
while playing Esus2, hit the low E and A strings more than the other strings.

Verse:
E  Esus2    E  Esus2      E           Esus2   (same chord progression until Chorus)
Life   is sweet   in the belly of the beast
In the belly of the beast
And with her song in your heart, it can never bring you down
It can never bring you do-own

Lost in a maze of a thousand rainy days
Of a thousand rainy days
But when I heard her voice, oh, it let me to the end
Yes it led me to the end

Chorus:
                 C#m            Abm
'Cause when she sings I hear a symphony
          A                      E
And I'm swallowed in sound as it echoes through me
     C#m                Abm
I'm renewed, oh, how I feel alive!
        A                          A
Through autumn's advancing, we'll stay young, go dancing

(riff)

Bridge:
B            F#m    B               C#m   A
As the music plays, feel our bodies swa-a-ay
B               F#m          A
When we move as one, we stay young...

Verse:
Life is sweet in the belly of the beast
In the belly of the beast
And with her song in your heart, it could never bring you down
It could never bring you down

Final Chorus:
                 C#m            Abm
'Cause when she sings I hear a symphony
          A                      E
And I'm swallowed in sound as it echoes through me
     C#m                Abm
I'm renewed, oh, how I feel alive!
        A                          A
Through winter's advancing, we'll stay young, go dancing
Stay young, go dancing
Stay young, go dancing (end on E chord)
