Nonono, y'all have got it wrong! (no offense). The way to play is in drop D tuning (in other words, D A D G B D from bass to top string), using slash chords for the main riff, like so:
D --0--0--0--0--0-----|--0--0--0-----------|
B --3--3--3--3--3-----|--3--3--3-----------|
G --2--2--2--2--2-----|--2--2--2-----------|
D --0--0--0--0--0-----|--0--0*-0-----------|
A --3-----------------|--3--2--0-----------|
D --------------------|-----------3-----5--|
* This D/B chord can be a bitch to reach while playing at any speed, so oftentimes I'll just play an easier Em11/B: x22230

Anyway, here are the verses:

D     = xx0320
Am7   = x02210
Cadd9 = x32010
G/B   = x20030
D5    = 000xxx
F5    = 333xxx
G5    = 555xxx
C     = xxx555
D     = xxx777
C11   = x32030
Cmaj9 = x32000
F/A   = x0321x
Gm7   = 355333
A7    = 577655

(arpeggiate chords for best results)
D                     Am7
I wanna live with the cinnamon girl
Cadd9                G/B
I could be happy the rest of my life
         D5 F5 G5 C D    C11 Cmaj9 C11 F/A
With the cinnamon girl

(as above:)
A dreamer of pictures I run in the night
You'll see us together chasing the moonlight
My cinnamon girl

(lather, rinse, and repeat, until you reach:)

Cadd9
Ma send me money, now
Cadd9
I'm gonna make it somehow
Cadd9            Gm7
I need another chance
Gm7                        A7
You see your baby loves to dance...

(and the greatest solo ever:)
D---0-0-0-0-0-0-----0-0-0-0-0-0-0-
B-3-3-3-3-3-3-3---3-3-3-3-3-3-3-3- you get the idea.
G---------------------------------
D---------------------------------
A---------------------------------
D---------------------------------

And, last of all, how could you forget the coda:
D-----(0)----------(0)----------(0)-----------(0)----0--
B------3------------3------------3-------------3-----2--
G------2------------2------------2h3p2---------2h3p2-3--
D------0--------0h3-0--------0h3-----------0h3-------0--
A--0h3------0h3----------0h3-----------0h3-----------0--
D----------------------------------------------------0--

D--------<7>---------<7>-
B-----<7>---------<7>----
G--<7>---------<7>-------
D--(0)-------------------
A--(0)-------------------
D--(0)-------------------

1h2 = hammer on
2p1 = pull off
(0) = let ring, without directly playing the string
<7> = harmonic (rest your finger on the string above the fret)
