Here are the English lyrics of Pepino's Friend Pasqual(as far as I can consume.)
Pepino, and just a little buddy, Pasqual, the Italian Pussycat.
Pasquale, say hello for me.
Buon Giorno!
Pepino, oh you crazy mouse why can't you let me be?
I sent that cat to chase you, now you've got him chasing me!
And when I try to sleep at night I can't get any rest.
Pasqual comes and licks my face while you dance on my chest.

I said Pasquale listen now, please help me catch that mouse!
My girlfriend's so afraid of him she won't come in the house!
But when I turn my back he steals the meatballs from the tray
And now that cat and mouse are playing gauche-ball all day!

Pepino, oh you crazy mouse why can't you let me be?
I sent that cat to chase you, now you've got him chasing me!
He's putting holes in all the floors and scratching up the walls
He's chasing all the neighbors down the stairs and through the halls!

Eurizi! Now what do you want?
We want to take your picture.
Oh! Like in Hollywood!
Pasquale: Stand against the wall.
Pepino: You ready?
Lou: Go ahead! Shoot!
(It turns out to be guns to shoot Lou, similar to one of Wile E. Coyote's attempts to catch the Road Runner in "Hot Rod and Reel"(1959).
