When he drops you off I will not say
E5      A5          E5            A5
Who was that who so quickly drove away
A5               F5 C5          G5             C5 FILL
The things you've done and the places you've been
E5              A5                  E5           A5 
When I open the door for you I will not let them in
A5                 F5          C5      G5      C5 FILL
As long as you come back to me I will never ask
E5             A5     E5              A5
For you I will be the man in the iron mask

BRIDGE FILL

A5          F5        C5      G5        C5 FILL     
You said you loved me and it broke my heart
E5                A5       E5             A5
I was always your prisoner right from the start
A5                      F5     C5     G5               C5 FILL
The nights you spend without me this house is like a dungeon
E5           A5        E5         A5
And you only return to torture me more
A5                F5       C5  G5        C5 FILL
You must have your reasons, I will not ask
E5             A5     E5              A5
For you I will be the man in the iron mask
