A quick note about the Amb7 found in the chorus: wasn't sure how to annotate it on here, that's a
half-diminished A7 chord. So, Am with a diminished seventh.

[Verse 1] 
C       Gm      F    C
Part of me has died
C       Gm    F    C
Won't return
C       Gm            F    C
Part of me wants to hide
C                 Gm    F    C
The part that's burned

[Bridge]
Am     D7
Once, once
F                C
I knew how to talk to you
Am     D7
Once, once
F             C
But not anymore

[Chorus]
Dm7                      Am7   G
Hear the sirens, call me home
Dm7                      Am7   Amb7
Hear the sirens, call me home
Dm7                      Am7   G
Hear the sirens, call me home
Dm7                      Am7
Hear the sirens, call me home

[Verse 2]
C       Gm      F    C
Part of me has died
C            Gm      F    C
to watch it burn
C                Gm        F    C
and the heart of me has tried
C                Gm      F    C
Look what it's become

[Bridge]
Am     D7
Once, once
F                C
I knew how to look for you
Am     D7
Once, once
F                C
But that was before
Am     D7
Once, once
F                             C
I would have laid down and died for you
Am     D7
Once, once
F             C
But not anymore

[Chorus]
Dm7                      Am7   G      _
Hear the sirens, call me home          |
Dm7                      Am7   Amb7    |- 2x
Hear the sirens, call me home         _|

Dm7                      Am7   G
Hear the sirens, call me home
Dm7                      Am7
Hear the sirens, call me home

[Outro]
C   Gm   F   C
