The Dean Martin recording is a halfstep lower but this key is more guitar-friendly.
The faux-italian lyrics may slightly vary between different versions of the song.

Dm                 Gm
A boy went back to Napoli
A                     Dm

Gm                         Bb
The native dances and the charming songs
   Bb              A7
But wait a minute something's wrong, 'cause now it's
 
Dm         Gm
