Chorus: Am      G       C 
        Am      G       F       Am
The C is played 3 3 2 0 1 0

There's also this rather handy fingerlift in the G that goes 3 0 0 0 0 3 into a hameron 3 2 0 0 0 1
Altogether, the riff looks roughly like this:

E|-----3-------------------0--|
B|-----0-------------------0--|
G|-----0-------------------0--|
D|-----0-------0-----------2--|
A|-----2--0h2-----2--------2--|
E|--3--3-------------3--0--0--| The base snares (E and B) are rather optional on the full chords.

This repeats on the Em, then switches to the C, with the hameron on the index finger before the chords repeat:

E|-------------------3--|
B|--0h1--------------0--|
G|-------0-----------0--|
D|----------2--------0--|
A|-------------3-----2--|
E|----------------3--3--| It goes back into G.

As for the lyrics...

Verse:
G        Em                C
I didn't have the heart to sell it
So I just gave your coat away
I took it to the Salvation Army
Where holy goners go to pray

I gave you my last drop of feeling
I made myself a shepherd's pie
And I've been sleeping in my blue jeans
I comb my hair to the other side

Chorus:
Am      G       C
I had a dream we were together
My baby blue, your boy in black
When you see your mother in Chicago
Am             G              F       Am
Tell her I'm happy to give you back

Verse:
I haven't smoked since I was fourteen years
I haven't lied since I was ten
But in my head I am a felon
I take a drag before I go to bed

I held your hand at the gravesite
Your beauty lost where your body lay
And the day I knew you would believe in me
I burned a tattoo on my leg

Chorus:
There's more air in Chicago
You can be on the other side
Because I'm not so good at failure
In case your mother asks you why

I had a dream we were together
My baby blue, your boy black
When you see your mother in Chicago
Tell her I'm happy to give you back
Tell her I'm happy to give you back
