Sweeney Todd (musical) - Barber and his wife

There was a barber and his wife,
And she was beautiful.
A foolish barber and his wife,
She was his reason and his life,
And she was beautiful,
And she was virtuous.
And he was... naive.

There was another man who saw
That she was beautiful,
A pious vulture of the law,
Who with a gesture of his claw
Removed the barber from his plate.

Then there was nothing but to wait
And she would fall,
So soft,
So young,
So lost,
And oh, so beautiful!

That was many years ago...
I doubt if anyone would know.
