Times for Military Music ?

Hi Gang!
Been here almost a week and time has flown, flown, flown!!
One inshore fishing trip with Julio's Tours done, going again in another couple of days for maybe something a little larger than this here 20 lb. Jack Crevall.... What's the deal with the military music I've been hearing some nights, from Centro? Is there a set schedule? Reminds me of those old French Foreign Legion movies....
