I spoke to Matt the lead singer and personally asked him how to play this song, and this is what he gave me:

[Intro]
E

[Verse]
    E
Now she hates having the main lights on
                                          A
But I try to tell her there's nothing wrong
           E
No there's nothing wrong with being alone
                                 A
But being alone is being without you

[Chorus]
   F#     A
So stay with me
           E
Woahhhhhhhhh
        B
Woahhhhhh
   F#     A
So stay with me
        E
Yeahhhhhh

[Verse]
    E
Now she hates when I hang around with other girls
                A
I know that you do
           E
No there's no one like you, no one like you
                                  A
Not even the early, early morning girl

[Chorus]
   F#        A
So stay with me
           E
Woahhhhhhhhh
        B
Woahhhhhh
   F#       A
So stay with me
        E
Yeahhhhhh

[Bridge]
(Very quiet and clean, then gets progressively louder and distorted)
   F#         A
So stay with me
     E
Come on
     B
Come on
   F#        A
So stay with me
     E
Come on
     B
Come on
   F#        A
So stay with me
        E
Yeahhhhhh

E

[Chorus]
   F#      A
So stay with me
           E
Woahhhhhhhhh
        B
Woahhhhhh
   F#        A
So stay with me
       E
Yeahhhhhh
