'Bambino'is actually a Neapolitan song called 'GUAGLIONE'

I almost fell off the couch watching the Hotel Nightclub scene. Dujardin starts playing the opening bars of his solo and immediately I recognize the song as "Guaglione", a classic Neapolitan song. What's interesting is that some Neapolitan songs have an unmistakable middle eastern influence to them. When he started singing the lyrics in Arabic I just lost it. I thought it was absolutely brilliant! Genius! Loved it!! For anyone that enjoyed this scene as much as I did, the song listed in the credits as "BAMBINO" is actually entitled "GUAGLIONE" and has been recorded by many artists and was also featured in the Anthony Minghella directed film, "THE TALENTED MR. RIPLEY". Kudos to the OSS:117 filmmakers!
