Don't even try to argue this is all 100% correct, I wrote this song so this is it, I'm letting ya'll learn it, probly long before you'll hear it.  But it's copywrited so don't try to steal it.  Also, Colin usually just plays power chords on this and he plays the low F5 (133XXX), instead of the high one ([X][8][10][10][X][X])

Intro:
F2  C9  G  C9-G x4

F2   C9   G  C9-G
I know you
    F2 C9            G     C9-G
And I know I want to love you
    F2            C9            G         C9-G
But I just can't find a way to get to you
   F2       C9        G     C9-G
If you were only here right now

Chorus:
Am    C9            D
You remember those warm summer nights
Am      C9     D
When we were together
Am C9      D    
Under the moonlit sky
     Am       C  D
Why didn't I realize I loved you


Now I look back with deep regret
About how I never really stopped to think
But if I only knew
Things would've been different

[Chorus]

Bridge:
Am  D       G  C9
It felt so right
Am     D       G  C9
But I felt so bad
Am      D       G   C9
Will I see you again
Am      D       G   C9
Will I see you again

[Interlude (Over bridge chords)]

[Chorus x2]

End on F2

Chord diagram:
    E  A  D  G  B  e
F2--X  8  10 10 8  8  < can also be played XX3213, but that's not how we do it
C9--X  3  2  0  3  3  < often referred to as Cadd9
G---3  2  0  0  3  3
D---X  X  0  2  3  2
Am--X  0  2  2  1  0

That's it, not too hard
