Lyrics:

My heart is beating from me
I am standing all alone                         
Please call me only 
If you are coming come                          (Intro)
Waste another year flies by                     
Waste a night or two 
You taught me how to live                       

In the streets of shame
Where you've lost your dreams in the rain       (Verse 1)
There's no sign of hope
The stems and seeds of the last of the dope

There's a glow of light
The St. Jimmy is the spark in the night         (Verse 2)
Bearing gifts and trust
The fixture in the city of lust

What the hell's your name
Whats your pleasure what is your pain?          (Chorus)
Do you dream to much?
Do you think what you need is a crutch?

In the crowd of pain 
St. Jimmy comes without any shame               (Verse 3)
He says "We're ***ed up," but we're not the same
And mom and dad are the ones you can blame

Jimmy died today
He blew out his brains into the bay             (Chorus)
In the state of mind 
It's my own private suicide

D                 G         D
Jesus filling out paperwork now
G               A
At the facility on east 12th street
D                 G    D
He's not listenin to a word now
G                         A
He's in his own world and he's daydreaming

D                    G         D
He'd rather be doing something else now
G                               A
Cigarrettes and coffee with the underbelly
D                           G    D
His life's on the line with anxiety now
G                      A      D
And she had enough and he had plenty

Lyrics:

Well nobody cares
Well nobody cares                               (Intro) x2
Does anyone care 
If nobody cares?

Jesus filling out paperwork now
At the facility on East 12th Street
He's not listenin to a word now
He's in his own world and he's daydreaming
                                                (Part 1)
He'd rather be doing something else now
Cigarrettes and coffee with the underbelly
His life's on the line with anxiety now
And she had enough and he had plenty 


Somebody get me out of here
Anybody get me out of here                      (Part 2)
Somebody get me out of here
Get me the *** right out of here

So far away
I don't want to stay
Get me out of here right now
                                                (Part 3)
I just wanna be free
Is there a responsibility
Get me out of here right now

Ahhh ohh                               
Ahhh ohh                                        (Part 4)
Ahhh ohh
Ahhh ohh

This life like dream ain't for me                (Outro)

III.    Nobody Likes You
------------------------------------------------------------

Written and sung by Mike Dirnt.

Intro: D

Verse 1:

D          A         G            A
I fell asleep while watching Spike TV
      D          A
After 10 cups of coffee 
          G         A
And your still not here


Verse 2:

D             A
Dreaming of a song
     G             A
But something went wrong
        D          A
And you can't tell anyone
       G         A
'Cause you're not here

Pre-Chorus:

D              A
Left me here alone
         G               A
When I should have stayed home
      B          Db
After 10 cups of coffee
      D
I'm thinking 

Where'd you go?

Chorus:

D         A
Nobody likes you
G             A
Everyone left you  (Where'd you go?) 
D               A
They're all out without you
G      A
Havin' fun (Where'd you go?)

D         A
Everyone left you
G             A
Nobody likes you  (Where'd you go?)
D               A
They're all out without you
G      A
Havin' fun 

        
Where'd you go?

Lyrics:

I got a rock and roll band
I got a rock and roll life              (Verse 1)
I got a rock and roll girlfriend
And another ex-wife

I got a rock and roll house
I got a rock and roll car               (Verse 2)
I play the *** out the drums
And I can play the guitar

I got a kid in new york
I got a kid in the bay                  (Verse 3)
I haven't drank or smoked nothin'
In over 22 days

So get off my case
Off of my case                          (Outro)
Off of my case

Lyrics:

Here they come marching down the street
Like a desperation murmur of a heart beat       (Verse 1)
Coming back from the edge of town
Underneath their feet

The time has come and it going nowhere
Nobody ever said that life was fair now         (Verse 2)
Go-carts and guns are treasures they will bear
In the summer heat

The world is spinning
Around and around                               (Pre-Chorus)
Out of control again
From the 7-11 to the fear of breaking down

So send my love a Letterbomb
And visit me in hell                            (Chorus)
We're the ones going...
