This song is quite easy, exept it does sound so much better with the orchestra, 
it's pretty fun playing it.
Please comment to tell me what you think, bearing in mid this is my first tab.

Capo 2

Christine:
Em          Am           D           Em
Beneath the opera house, I know he?s there.
Em           Am            D         Em
He?s with me on the stage, he?s everywhere.
Em          Am           D       Em
And when my song begins, I always find,
Em                        Am
The phantom of the opera is there.
Am        Em
Inside my mind.

The phantom:
Em         Am           D             Em
Sing once again with me, our strange duet.
Em       Am             D        Em                     
My power over you grows stronger yet.
Em               Am          D           Em                        
You?ll give your love to me, for love is blind.
Em                         Am                 
The phantom of the opera is now,
Am         Em
Your mastermind.

Christine:
Em             Am              D            Em
Those who have seen your face, draw back in fear.
Em        Am            D            Em
I am the mask you wear; it?s me they hear.
Em          Am            D       Em
Your spirit and my voice, in one combine.
Em                           Am         
The phantom of the opera is there,
Am          Em         
Inside my mind.

Both:
Em       Am              D           Em
Sing once again with me, our strange duet,
The phantom:
Em      Am         D             Em
My power over you, grows stronger yet,
Both:
Em               Am          D           Em
You?ll give your love to me, for love is blind.
Em                          Am         
The phantom of the opera is now,
Am          Em
My mastermind.
