WHITE SHADOWS

Intro:

Organ: Abm
Full band: Abm  |  B  | C#m9 | Ebm (all over 
bass)


Verses

   Abm            B          Ebm    C#m(add9)
1. When I was a young boy I tried to listen
2. If you ever feel like something's missing
3. When I was a young boy, I tried to listen

Abm          B         Ebm
And I wanna feel like that
things you'll never understand
Don’t you wanna feel like that?

Abm            B         Ebm    C#m(add9)
Little white shadows, blink and miss them
Little white shadows, sparkle and glisten
You’re part of the human race, all of the stars in the outer space

Abm        B       Ebm
Part of a system, I am
Part of a system, a plan
Part of a system, I am


Interlude (after verse 1)
Abm  |  B  | C#m9 | Ebm (all over Ab bass)


Pre-chorus (after verses 2 and 3):

Emaj7                 C#m(add9)
All this noise I'm waking up
All this space I'm taking up
All this sound is breaking up
Ooh oh ooh____________

Chorus:

Abm                        Emaj7
Maybe you'll get what you wanted
B                    Ebm
Maybe you'll stumble upon it
Abm                  Emaj7
Everything you ever wanted
       B        Ebm
In a permanent state

Abm                        Emaj7
Maybe you'll know when you see it
B                            Ebm
Maybe if you say it you'll mean it
Abm                         Emaj7
And when you find it you'll keep it
        B        Ebm             Abm
In a permanent state, a permanent state

Outro: (organ only)

Abm
Swim out on a sea of faces
E                             B
The tide of the human races, oh
                         Ebm
An answer now is what I need
Abm
See it in the new sun rising and
E                             B
See it break on your horizon, oh
                        Ebm
Come on love, stay with me

G#m (fade out)
