Sine Bundgaard as Nedda and Fredrik Zetterström as Tonio in Copenhagen, December 2011 -- there are full English texts farther along in the post.
To deal for now with just the beginning:
When NEDDA finishes her Ballatella, she is startled to discover TONIO watching.
NEDDA [sharply interrupting her train of thought]: You're there? I thought you had gone.
TONIO: It's the fault of your singing.
Fascinated, I reveled in it.
NEDDA [mockingly]: Ha Ha! So much poetry!
TONIO: Don't laugh, Nedda!
NEDDA: Go! Go off to the inn!
TONIO: I know well that I am deformed,
I am contorted,
that I arouse only scorn and horror.
Yet my thoughts know dreams, desires,
a beating of the heart.
When so disdainfully you pass me by,
you don't know what tears
grief forces out of me!
Because, in spite of myself,
I've suffered enchantment,
I've been conquered by love!
[Moving closer to her]
Oh! let me tell you --
NEDDA [interrupting]: That you love me?
Ha ha ha ha!

The YouTube clip has the full Nedda-Tonio scene, which as you can see isn't a long one. In Friday night's preview, we got only as far as the audio clips above, through Tonio's declaration of love to Nedda, and at that we left out the first couple of lines.
IT'S NOT A PRETTY SCENE
We've reached the point in our look at the situation of poor Nedda in I Pagliacci, where she has to deal with this unwelcome suitor. I don't think we need to say much more about the scene, but just let it unfurl. It's not a pretty scene, and while Nedda can certainly be understood for her actions, since Tonio really leaves her little choice, refusing to abandon his suit. Still, one remembers that her immediate reaction to his pouring his guts out is ridicule and scorn.
