This is not the official key, or exactly the 'real' version.
But it's a simplistic version to get started.
[Verse]
Dsus2 D Dsus2 D Dsus4 Am7
Sitting on the floor and talking 'til dawn
A7sus2 Am7 D
Candles and confidences
Dsus2 D Dsus2 D D Am7
Trading old beliefs and humming old songs
Am7 D
And lowering old defenses
[Chorus]
G Gmaj7
Singing a love song, la la la la
F#m Bm
La la le la la la
Em G
Love song, la la le la
[Verse]
Dsus2 D Dsus2 D Dsus4 Am7
Private little jokes and silly pet names
A7sus2 Am7 D
Lavender soap and lotion
Dsus2 D Dsus2 D D Am7
All of the clichés and all of the games
Am7 D
And all of the strange emotions
[Chorus]
G Gmaj7
Singing a love song, la la la la
F#m Bm
La la le la la la
Em G
Love song, la la le la
[Bridge]
D
They say the whole is greater
Cmaj7
Than the sum of the parts it's made of
D C#m
Well, if its true of anything
A A7
It's true of love
[Verse]
Dsus2 D Dsus2 D Dsus4 Am7
'Cause how can you define a look or a touch?
A7sus2 Am7 D
How can you weigh a feeling
Dsus2 D Dsus2 D D Am7
Taken by themselves now they don't mean much
Am7 D
Together they send you reeling
[Chorus]
G Gmaj7
Into a love song, la le la la
F#m Bm
La la le la la la
Em G
Love song, la la le la la
Dsus2 D Dsus2 D Dsus4 Am7
La le la la la la le la la la
A7sus2 Am7
Dsus2 D Dsus2 D Dsus4 Am7
La le la la la la le la la la
