This is my first-ever tab; I listened to Tre! and I absolutely fell in love with 
it (and every other song by Green Day). This is a really great song, and so I had 
to tab it. The chords are fairly easy:

E B C#m A 

Try to figure out the strum pattern, it's really fun. Enjoy, rate, and comment! 

E          B
Hey, little kid 
       C#m                   A
Did you wake up late one day and 
                E                    B
You're not so young, but you're still dumb 
            C#m                  A
And you're numb to your old glory but now it's gone 


E           B          C#m                A
I fell in love, but it didn't catch your fall 
         E              C#
Then I crashed, into a wall 
         B                 A
Then I fell to pieces on the floor 
                 A    E
Now you're sick to death 


E       B              C#m
Bombs away, here goes nothing 
               A
The shouting's over 
       E           B
Hey X-Kid, bombs away 
           C#m
Here goes nothing 
                A
The shouting's over and out  
             B    E        B    C#m A
Over and out again 


   E            B 
I once was old enough 
          C#             A               E
To know better, man I was too young to care 
      B                    C#m
Many cares, probably would but 
        E/A
Harvey Wood is dead and gone 


E           C#m          B              A   
You fell in love but then you just fell apart 
        E           B
Like a kick in the head 
          C#m                  A                    B                E
You?re an X-Kid and you never even got started again 


        B             C#m
Bombs away, here goes nothing 
               A
The shouting's over 
       E           B
Hey X-Kid, bombs away 
           C#m
Here goes nothing 
               A
The shouting's over and out 

Over and out 


A   E   B
            And you were such a young soul 
A   E   B                        A               B
            And you got lost and out of control 
B                     A
    You went over the edge of joking 
          E             A
And died of a broken heart 


E          B
Hey, little kid 
         C#m               A
Did you wake up late one day and 
                E                        B  
You're not so young, but you're still dumb 
         C#m           A                          B        E
You?re an X-Kid and you never even got started again 



        B             C#m
Bombs away, here goes nothing 
               A
The shouting's over 
       E           B
Hey X-Kid, bombs away
          C#m
here goes nothing 
               A
The shouting's over 
       B              E
Hey X-Kid, bombs away
