[Intro]
Am C F 
[Strophe]
Am          C                F
 I can't believe the news today
Am         C                F 
 I can't close my eyes and make it go away
C               Dm
 How long? How long must we sing this song?
C               Dm
 How long? How long?...
          Am    C F
'Cause tonight,   we can be as one
   Am    C F
tonight.
Am       C              F 
 Broken bottles under children's feet
Am         C               F
 Bodies strewn across the dead-end street
Am      C              F 
 But I won't heed the battle call
Am           C                F 
 It puts my back up, puts my back up against the wall
[Refrain]
Am   C           F 
 Sunday, Bloody Sunday
Am   C           F 
 Sunday, Bloody Sunday
Am   C           F 
 Sunday, Bloody Sunday
Am   C           F 
 Sunday, Bloody Sunday

Oh, let's go
[Strophe]
Am        C               F 
 And the battle's just begun
Am        C              F 
 There's many lost, but tell me who has won?
Am             C              F 
 The trenches dug within our hearts
Am              C                  F 
 And mothers, children, brothers, sisters torn apart
[Refrain]
Am   C           F 
 Sunday, Bloody Sunday
Am   C           F 
 Sunday, Bloody Sunday
C               Dm 
 How long? How long must we sing this song?
C               Dm  
 How long? How long?...
          Am    C F                    
'Cause tonight,   we can be as one
   Am    C F
tonight 
   Am    C F
 tonight
Am   C           F  
 Sunday, Bloody Sunday

[Strophe]
                Am        C    F
Wipe your tears from your eyes
           Am    C   F
Wipe your tears away
                Am    C   F
I'll wipe your tears away
                Am    C   F 
I'll wipe your tears away
                Am        C   F 
I'll wipe your bloodshot eyes
[Refrain]
Am   C           F  
 Sunday, Bloody Sunday
Am   C           F  
 Sunday, Bloody Sunday
[Strophe]
Am          C            F 
 And it's true we are immune
Am              C      F 
 When fact is fiction TV is reality
Am      C                 F 
 And today the millions cry
Am            C            F 
 We eat and drink while tomorrow they die
Am         C               F 
 The real battle's just begun
Am             C             F 
 To claim the victory Jesus won

On...
[Outro]
Am   C           F   
 Sunday, Bloody Sunday
Am   C           F   
 Sunday, Bloody Sunday
