VERSE

A5    F5    G5      A5
Oooh Oooh Ooooh Ooooh


A5        F5
I'm the obsessor
G5            A5
Holding your hand
                   F5
It seems you have forgotten
G5           A5
About your man
              F5
Alone in the darkness
G5                     A5
My bed's a different land
           F5
Your touch intensifies

CHORUS
G5              A5        F5   G5   A5
And I'm in the Quicksand
           F5         G5    A5
I'm in the Quicksand
           G5        A5   F5    G5
I'm in the Quicksand

VERSE
A5         F5
You're the upsetter
G5           A5
Stroking my hand
          F5
What's my position?
G5       A5
I don't understand
          F5
Am I your possession?
G5       A5
Am I in demand?
             F5
Oh when you turn to me

CHORUS
G5          A5        F5     G5    A5
I'm in the Quicksand
           F5         G5    A5
I'm in the Quicksand
           G5         A5    F5     G5
I'm in the Quicksand
 
BRIDGE
A5                     G5
You, you moved into my mind again
A5                               G5    
You, you're walking around rent free Oooh
A5    G5
Oh I could let you stay
          C5                 A5
But I'm walking on broken ground again
       G5
Oh oh when will I learn?
C5                     A5
All you do is kick me back in the dirt
 

A5      G5      C5    A5
Ooooh Oooooh Ooooh ooooh
       G5     C5
Oooh Ooooh Ooooh (x2)
