Decided to upload the whole thing after all. This is the Original Concept Recording of 1994 (the amazing Anthony Warlow as Jekyll/Hyde). I numbered all of them as to make it easier to listen through the whole thing from start to finish. Enjoy! :)

Update:
Someone reminded me (6 years after I promised to do so, haha) to put the lyrics in the descripton, so here they are:

[STRIDE]
Lisa Carew, can this be you?
What kind of man is this you've taken?
Can you not see the kind of life
That this would be? You are mistaken!
Time to awaken before it's too late
Before you forever determine you fate!

[LISA]
But Simon, you knew: I had to be free
What I choose to do is decided by me!

Ever since my mother died
My father, bless his darling heart
Has treated me as though I'm still a young child
Maybe his idea was just to wait until I grew up
And then look at me and hope that I'd be her

It's easy to accept this from a father
He'd rather things remained the way they were
But when it comes to marriage, I must pick whom I prefer!
I am not the weak young thing you're seeking, Simon
Someone seventeen, obedient and sweet
I am not the protégé to waste your time on, I'm complete!

In Henry's eyes I see what I am meant to be

[STRIDE]
Lisa, listen to me!

[LISA]
Simon, enough!
There's nothing more!
Don't be a bore!
You have your answer!

That's how things are!
Will always be!
You had your chance, Sir, with me!

[STRIDE]
Someday you'll regret what you just said to me!
Lisa...

[LISA]
We'll see, Sir!
