Christine (Sarah)
Beneath the opera house
I know he's there.
He's with me on the stage,
He's everywhere.
And when my song begins,
I always find
The phantom of the opera is there
Inside my mind.
The phantom (Steve)
Sing once again with me
Our strange duet.
My power over you
Grows stronger yet.
You'll give your love to me
For love is blind.
The phantom of the opera is now
Your mastermind.
Christine
Those who have seen your face
Draw back in fear;
I am the mask you wear,
The phantom
It's me they hear.
Christine / Phantom
Your/My spirit and my/your voice
In [bad word] 
The phantom of the opera is there
Inside my/your mind
Choir (very, very soft)
The phantom of the opera
Is there
The phantom of the opera
The phantom
Sing once again with me
Our strange duet.
My power over you
Grows stronger yet.
Christine / Phantom
I'll/You'll give my/your love to you/me
For love is blind.
The phantom of the opera is now
My/Your mastermind.
The phantom (spoken)
Sing, my angel of music ...
Christine
He's there,
The phantom of the opera.
Christine starts wailing
The phantom (spoken)

Sing ...
Once again with me, our strange duet.
My power over you grows stronger and stronger.
Sing ...
My angel of music/
Sing!
Sing our strange duet -
Sing!
Christine continues wailing,
and keeps on wailing after every
sentence the Phantom sings
The phantom (spoken)

The phantom of the opera
Is now your mastermind;
I am here, inside your mind!
I am everywhere!
You're in my power.
Sing!
Sing, my angel of music!
Sing! Sing!
