Queen Bitch Chords by David Bowie

I saw the other tabs for this when trying to learn it & realised they are horribly wrong!!!
This is the 100% correct tab for this song, as:
1. Im a HUGE Bowie fan.
2. Im sure it's right.
3. I've seen him play the song after coming up with this & i am right.

I do not know the names for the variations of the C shape so i'll label them: (please 
the names of the chords if you know them as comments).

David Bowie played this on a 12-string acoustic, but will sound similar on a normal, 
not as exact.

Standard Tuning:

C1:          C1m:
e|-0----|    e|-0----|
B|-1----|    B|-1----|
G|-0----|    G|-0----|
D|-2----|    D|-0----|
A|-3----|    A|-3----|
E|-3----|    E|-3----|

C2:          C2m:
e|-0----|    e|-0----|
B|-1----|    B|-1----|
G|-2----|    G|-0----|
D|-3----|    D|-3----|
A|-3----|    A|-3----|
E|-0----|    E|-0----|


C3:
e|-0----|
B|-3----|
G|-4----|
D|-5----|
A|-5----|
E|-0----|

The intro therefore goes:

C1,C1,C3,C2,C1,C1,C1,C3,C2 & repeat.

(slide on the way through)
  C1      C3  C2  C1     C3  C2
e|-0--0---0---0----0--0--0---0---0-|
B|-1--1---3---1----1--1--1---3---1-|
G|-0--0---4---2----0--0--0---4---2-|
D|-2--2---5---3----2--2--2---5---3-|
A|-3--3---5---3----3--3--3---5---3-|
E|-3--3---0---0----3--3--3---0---0-| (intro & riff)

Repeat the intro 4 times, electric guitar kicks in after 2 repetitions.
Then it's as follows:

-strumming-

C1            C1m (let go with the middle finger softly)
I'm up on the eleventh floor
C2            C2m                    
And I'm watching the cruisers below
C1            C1m
My heart's in the basement
C2        C2m                        
My weekend's at an all time low
C1        C1m
He's down on the street
C2                 C2m                  
And he's trying hard to pull sister Flo
C1                 C1m
 'Cause she's hoping to score
C2                 C2              
 So I can't see her letting him go
E
Walk out of her heart
F                 G
Walk out of her mind

[CHORUS]
B                                  D
She's so swishy in her satin and tat
B                                         D
In her frock coat and bipperty-bopperty hat
B      (no strum)
Oh God, I could do better than that

Riff x 4

The same pattern then continues throughout
