I had the chance to attend the premiere of Massaniello at Teatro Bellini in Naples.
Wonderful music and lyrics by Tato Russo, although most of the parts are in napolitan dialect.
I really liked Ariadna, in the role of Bernardin, Massaniello's wife.
If you have the opportunity to see this musical, I am sure you will enjoy it.
<Added>Sorry about the name. There are several versions of the story of this popular hero of 1647 Naples.
The one I refer to is Masaniello and the link to visit a site related to it is:
