I strum the intro something like this : (all downward strums except
the third chord which is strummed upward). I don't know what chord it is.
As you can see, I'm pretty hopeless at tabulature but I'm sure if you hear 
the song, you can figure what the tab below means! 
                                        
        --2-2-3---2-2-3-
        --3-3-3---3-3-3-
        --2-2-2---2-2-2-
        ----------------
        ----------------
        ----------------

There is also another chord which is like a D so I'll call it D*.
It is played by :
                        ---2---
                        ---2---
                        ---2---
                        -------
                        -------
                        -------

                The Tower - Chris de Burgh


D5                                       D5 * 
A great lord came walking through the forest one morning
        G5               D5
With a weapon in his hand
                           D5 *
Rich was his castle, he lacked for nothing
    G5               A5
Killing was his plan
        B5                      F#5
When a white bird flew by, she fell from the sky
  G5             D5         E5            A5               D5
Nothing was found, only blood on the ground, she was gone


D5                         D5 *                    G5               D5
Cursing his fortune, he turned to the forest to kill once again
                              D5 *                        G5            A5   
Standing before him was a lovely young woman with her head hung in pain
              B5                   F#5
When he saw her, his eyes were filled with desire
      G5                 D5    E5            A5
He said "I must have her, she must be mine
                D5 G5 A5
She will be mine"

D5                            D5 * 
He offered her silver, he offered her gold
            G5                D5   
But she threw it on the ground
                                D5 *
He fell to his knees and he begged her, "Oh please
            G5                             D5
Come with me, what you wish will be found"
        B5                          F#5
She said, "Sir, I'll go if you'll put up your bow
    G5           D5       E5              A5
Spare these creatures, leave them in peace
                F#5
You have no need

          E5         A5              D5   
But her words were lost in the wind
      G5         D5           A5    
His eyes were fixed on a queen 
     B5                 F#5     E5      A5             D5  
And all he saw was a woman but all she was, was a dream
B5 F#5 G5 B5 F#5 E5 A5
Da-ah
   B5             F#5        E5      A5           D5             
All he saw was a woman and all she was, was a dream

Other verses :
He took her and bound her with ropes tied around her
To his castle he did ride
In the wood was a bower where stood an an old tower
And he threw her deep inside
And the birds left the sky and a terrible cry 
Brought thunder and lightning, rain falling down
Tears on the ground

All through the days on her face he would gaze
For she was lovely as the spring
No words would she speaketh but leave them in peace
And some sad lament she would sing
One day by the door, through the window he saw
A single white feather lying on the floor
She was there no more

Now that great lord is dying, his cold heart is crying
For the love of a girl
For many an hour he has wept on the tower
For she meant more than the world
One day in the sky a white bird flew by
He lifted his hands, he cried out in pain
Come back again

But his words were lost in the wind
His castle was built upon sand
All he saw was her memory
And all he yearned was her hand
Da  aa
All she was, was a memory
And all he yearned was her hand
