Campochiaro is located in the Province of Campobasso, immediately to the south of Colle d'Anchise, just east of San Polo Matese, and just west of Guardiaregia. This is a video from Campochiaro from 2012, courtesy of Molise Web TV, with a very short song at the very beginning from 0:16 to about 0:44 and some lines from an outdoor play(?) being sung from 4:12 to 5:12. I think the songs are all in Molisan, though of course, the report in the middle and after all the songs are not (they're in Standard Italian, albeit IINM with a noticeable Molisan accent):
