I wrote down these lyrics by ear and they've not been verified by PhantomReviewer (except for the Les Miserables bit which I originally could only partially figure out.) But I link to the original video after the lyrics so you can check the lyrics from there. And I recommend to listen to it anyway because this is even more hilarious the way they sing this. :D

PhantomReviwer's version of 'Beneath A Moonless Sky':

P: ”So, ten years ago,
it seems we got it on.
That's what Lloyd Webber said.
That's why we have this song.”

C: ”I came back to you.
I'm not sure why I did.
It's yet more doubtful still
that I knew where you hid.
It was black there...”

P: ”It was dark there...”

C: ”...and I couldn't see you standing there...”

P: ”If I had known what's up, I'd have lost the candles in my lair.”

C: ”And I kissed you!”

P: ”Wait, did what?”

C: ”Yes, I kissed you!”

P: ”Oh, it's crypted!”

C: ”And it seems we made out then and there.”

P: ”You'd think that you would feel my face and lack of hair.”

C: ”But yes, I must confess,
I was too drunk to care.
I didn't like the dark,
a thought occured to me;
if you'd just worn your mask,
I'd still not have to see.
A paper bag would do, it's far less dangerous
than screwing in some barn
with livestock watching us.”

P: ”Aaaand I fucked you!”

C: ”And you groped me!”

P: ”And I ploughed you.”

C: ”Aaanyone who passed by was confused.
I think the sounds we made
were in the morning news.
And I banged you!”

P: ”And I shagged you.”

C: ”And I humped you.”

C&P: ”And we switched positions now and then.
We looked and found some things for which we each could beg.”

C: ”We made a mockery of
the original sad end.
...Buuut I was horny! So very horny!”

P: ”And you knew I wouldn't turn you down.”

C: ”Admit it, you were thrilled!”

P: ”And did you see me frown?
...When the sun came up,
I had a burst of shame.
So I abandoned you,
to cope with all the blame.
I ran the hell away.
I couldn't deal with this.
Recall how much I freaked
at just that little kiss.”

C: ”SO you ditched me!”

P: ”Wait! You ditched ME!
After everything I did for you,
you risked making my life
Les Miserables come true.
But I loved you!”

C: ”You're a douchebag!”

P: ”You left me first and we should not have shagged at all!”

C: ”No, not at all!”

C&P: ”There's nothing in Leroux...”
C: ”...about sex against the wall.”

The video I typed those lyrics from is link.
(The song starts at the point of 11 minutes. But the entire review is worth watching, all the four parts. And it's worth watching to anyone interested in LND, not just LND haters.)

Like PhantomReviewer, I too do like the music of 'Beneath A Moonless Sky', but good grief the lyrics! Not to mention the plot point in itself...
