Most notes in the Verse and Chorus are palm muted to make more space for the voice.
As for all the hammer ons and pull offs in the Main theme - figure it out yourself by
listening to the song. He plays some variations i couldn't quite figure out. But i think
it's good enough as it is.

[Verse #1]
Em   C/G     G   Asus2           Em  C/G  G
I am nobody  ,   nobody is who I am
G                    Em       C/G
  I am a traveler on this land
C/G  Asus2
And nothing, nothing in my hands

I am nobody, nobody is who I am
I am a wanderer on these sands
And I got down on my knees and folded my hands

Em (all the way)
And on the great wings of a great bird
I was carried to a temple
Where I heard the word...

[Chorus]
Dead man on the run, him and his shotgun
Panic in the street, testing one two three
Simple is the song- sing to carry on
Dead man on the run, him and his shotgun

[Bridge]
c  D  E x2


[Verse #2]
Uhhuuh x2
I am nobody, nobody is who I am
Through the red sky on the crow's wing I stand
And now to the radiant sun I surrender myself again
Then higher through the fire and to Orion with the raven
I look into the eyes...


[Chorus]
Dead man on the run, him and his shotgun
Panic in the street, testing one two three
Simple is the song- sing to carry on
Dead man on the run, him and his shotgun


[Bridge2]
Uh uh uh (like tabs above) x4

Main Theme played over Chorus
[Chorus]
I am nobody, nobody is who I am
Through the red sky on the crow's wing I stand
And now to the radiant sun I surrender myself again
Then higher through the fire and to Orion with the raven
I look into the eyes...
