First, "la banda del poli castellano" – that translates from Spanish to something like "the Castilian police band" or "the Castellon police band." Maybe it's a name of a group or a band related to the police in Castile, Spain? But "Castellano" usually refers to Castile, a region in Spain. However, sometimes in Latin America, it might refer to something else. Wait, "banda" in Spanish can mean a group or a band, like a musical band, but it can also refer to a group of people.
