Did anyone have any at their wedding? I'm a redneck and I come from a whole family of NASCAR fans

but FI is Hispanic (you would never know by looking at him lol) but he has hinted a few times how he's wanted mariachis at the reception but knows my family will be kind of caught off gaurd. I think he deserves what he wants for our wedding day so thinking about having them come for an hour or two. Any recs? What would you do in this situation?
