Commercial Song in Italian

[shortendtwizzler]

Okay, bare with me. I just saw this commercial a few days ago and haven't seen it since. It starts off with two old men singing a song in Italian and they are talking back and forth with the lyrics. They eventually join the rest of the town at the end of the commercial where they are all engaged in conversation in song and dancing. The song sounds familiar but I can't place it. Please help, Thanks.
