My medley weaves in and out of several songs, starting with:
Think of me
All I ask of you
Music of the night
Wishing you were somehow here again
Phantom of the Opera (Main theme)
Masquerade
(reprise)Music of the night

I play the first 4 numbers with just piano and strings, no rhythm, then when the pipe organ kicks in, I use a Rock rhythm and do the Main theme and a few little visitations of prior melodies before the climax ... then an abrupt cut .....
and I go back to the piano/strings to gentley articulate the ending, much the same as the ending in the original score ...
It's awesome stuff to play... the extreme changes in tempo and volume, the dynamics of it all is such a rush for me.

As the last note is fading, slowly .... the room is usualy SO quiet that they seem to be waiting for a curtain to drop!
There's NO business like show business, right Ethyl?
