ROBBIE WILLIAMS ? COME UNDONE

-Verse 1-
B                     
So unimpressed but so in awe
E
Such a saint but such a whore
B
So self aware so full of s**t
E
So indecisive so adamant

-Bridge-
F#                            E
I'm contemplating thinking about thinking
F#                               E
It's overrated just get another drink and
E
Watch me come undone

-Chorus-
B                                 E
They're selling razor blades and mirrors in the street
B                            E
I pray that when I'm coming down you'll be asleep
B                         E
If I ever hurt you your revenge will be so sweet
            C#m                E
Because I'm scum, and I'm your son,
E        B
I come undone
E        B
I come undone

-Verse 2-
B
So rock and roll, so corporate suit
E
So damn ugly, so damn cute
B
So well-trained, so animal
E
So need your love, so f**k you all
F# 
I'm not scared of dying 
         	   E
I just don't want to
        F#                      E
If I?d stop lying I'd just disappoint you

I come undone

-Chorus-

So write another ballad 
A
Mix it on a Wednesday
E
Sell it on a Thursday 
E
Buy a yacht by Sunday
B
It's a love song
B
A love song
A
Do another interview
A
Sing a bunch of lies
E
Tell about celebrities that I despise

And sing love songs
          F#
We sing love songs
