I Nomadi's "Mama Giustizia" is used about 500 times throughout "No, Il Caso e Felicemente Risolto" - If it wasn't such a great tune I'd say that was overkill - I mean it really is used in practically every scene (either the tune itself or a variation of it)
The song seemed to have done decent business back in the day and I Nomadi still play it at gigs after all these years. Co-written by Riz Ortolani, I believe.
Personally, I like it, but I can see someone saying it's a bit much...

Fantastic song - but damn! that is some seriously bad attempt at singing in English... it is WAY off key throughout. Again, though, it's saved by the fact that musical arrangement is actually very good, I mean, it IS a nice tune...
Something tells me Riz Ortolani probably got her the deal because she was his wife... or he didn't have a fucking clue she was singing completely out of tune.
