okay, so I submitted version 2 chords for
regular Hum The Tune, then I got the album
and realised that it's a different version 
on there so... I'm gonna submit it here as 
the acoustic version. Tabbed from the 
chords that Ed told me via Youtube comment. :P 


Standard Tuning with a capo on 5TH FRET.
All chords are relevant to capo.

Intro: Am, C, G x2

Verse 1:

Am             C                 G  
Sometimes you write a song that you can't sing
Am                        C                       G         
'cause the subject matter raises something that you kept in the dark
Am    C                 G
Well maybe you'll sing her name
G         Am              C
maybe it doesn't really matter what you say
G                                           F
because you've said now you can't sing it out loud


Chorus:
Am                 C         G
If it needs to be said then say it
                             G
If it needs to be sung don't hesitate
Am                      C
But if you wrote it and now you regret it 
      G      
well hum the tune
Am       C        G
Na na na na na na na
Am       C        G
Na na na na na na na


Verse 2:
Am                      C               G
This is a song for the ones who feel betrayed
Am               C          G
But not enough to lose her friends
Am                           C                 G  
A song for the ones with a hidden past who kept it in the dark too long


Pre-Chorus:
Am                     C                 G
This song's about the girl that doesn't know that he's in love with her
Am                       C                   F
And the boy who doesn't know she loves him too


Chorus:  (x2)
Am                 C         G
If it needs to be said then say it
                             G
If it needs to be sung don't hesitate
Am                      C
But if you wrote it and now you regret it 
            G
well hum the tune  (hum it now)
Am       C        G
Na na na na na na na
Am       C        G
Na na na na na na na

Outro:
Am       C        G
Na na na na na na na
Am       C        G
Na na na na na na na
Am       C        G
Na na na na na na na
Am       C        G
Na na na na na na na
Am       C        G
