Tuleto
The correct spelling is Toledo - it is a place in Naples, in which it was usual - even now, I believe - to walk with the girlfriend.
I don't know if you realized that the song is in the dialect of Naples.
There is another popular song about Toledo, interesting because it shows which was the culture in Italy :
Io mammeta e tu
passeggiamme pe' Tuledo
nuie avanti e mammeta arretro

Io tu e tua madre
were walking in Toledo,
we ahead end your mother back

The mother was following and checking the behaviour of her daughter.
