O.K. I see the need for a little help with translation.

By the light of the moon my friend Pierrot,
Lend me your pen for to write a word,
may lamp is dead, I have no more fire.
Open your door for the love of God.

By the light of the moon Pierrot replied,
I have no pen, I have no fire.
Go to the neighbor, I believe she is there,
For in the kitchen, someone's building a fire.

By the light of the moon the friendly Lubin
knocked on the brunette's door and she replied suddenly,
"Who's knocking at my door?" and he replied in turn,
"Open your door for the love of God"

By the light of the moon, one couldn't see much there
they looked for the pen, they looked for some fire.
In looking for thoses things, I don't know if they were found,
But I know that the door shut behind them.

I hope this is helpful.
