That's not even Italian, it is Naples Dialect. I'm Italian and yes, I totally agree..Darren singing this is the sexiest thing ever! And his Italian accent is very good!
In the middle he's saying: 'are there any italians tonight? Sorry, my italian's not perfect'. And yes, this is a very famous dialect in Italy, but it's very difficult to understand, even if u r italian like me :) but this song is know mostly by everyone here in italy, so... anyway, that is the proof that everything sounds better in italian :D love uuu Darren ♡
he says :"tonight there are italian here?" and people says yes, and then he apologize because he says that his italian is not perfect. (wich is totally not true) sorry for my english, i'm from italy, and i'm not good like darren criss with languages ;)
