Isaac play this song with a 12 strings guitar, but it sounds good with a six strings 
:) I watched him play in Underneath Acoustic live so I'm preatty sure, just the tempo it's 
little bit difficult to get.


intro

D G D A

D                  G
You who are on the road
            D                  A
Must have a code that you can live by
    D             G
And so become yourself
            D              A
Because the past is just a goodbye.
D                    G
Teach your children well,
               D               A
Their father's hell did slowly go by
   D                  G
And feed them on your dreams
             D                      A
The one they picked, the one you'll know by.

(beware that tempo changes)
D                       G
Don't you ever ask them why, if they told you, you
      D                            Bm   G  A (mute)
would cry,So just look at them and sigh
               D         G A (mute)
and know they love you.
    D               G
And you, of tender years,Can't know
    D                      A              D
the fears that your elders grew by,And so please help them
          G                   D                 A
with your youth,They seek the truth before they can die.
D                  G
Teach your parents well,Their
           D                A           D
children's hell will slowly go by,And feed them on
       G                 D                       A
your dreamsThe one they picked,  the one you'll know by.

(tempo changes)
D                       G
Don't you ever ask them why, if they told
              D                             Bm   G A (mute)
you, you would cry,So just look at them and sigh
     D                    G  A  (mute)
and know they love you
    strum D
and know they love you.
