I think this is pretty accurate:
C/B is where you slide your 4th finger from the standard C position into the second fret
(Still on the A string)
Verse 1:
C C/B C
All i want is nothing more
C/B Am
To hear you knocking at my door
F C
Cause if i could see your face once more
C/B Am
I could die a happy man, I'm sure.
Verse 2:
C C/B C
When you said your last good-bye
C/B Am
I died a little bit inside
F C
I lay in tears in bed all night
[ Tab from: https://www.guitartabs.cc/tabs/k/kodaline/all_i_want_crd_ver_3.html ]
Am C
Alone without you by my side
Chorus:
Am
But if you loved me
F
Why'd you leave me?
C
Take my body
G
Take my body
Am
All i want is
F
& all i need is
C
To find somebody
G
I'll find somebody...
C C/B C
Like you oohh oohh
C C/B Am
You, oohh oohh
F C
Am C
Verse 3: (Same as Verse 1&2)
See, you brought out the best of me
A part of me I've never seen
You took my soul & wiped it clean
Our love was made for movie screens
Chorus: (Same as above)
But if you loved me
Why'd you leave me?
Take my body
Take my body
All i want is
All i need is
To find somebody
I'll find somebody...
