Try this: Next time you're driving home superlate on a Saturday night, just grazing the legal alcohol limit, tune the radio to 91.3 (yes, South Florida's NPR news station) and turn the volume up, way up. Suddenly you're part of a family of late-night wanderers united by a love of Caribbean music and a subtropical nighttime bliss that stretches over silken airwaves from Homestead to Grand Bahama. "The Man Inside Your Radio," Davis lays down a backing track at the top of the hour (the toppa the arr, in his lullaby island brogue) and devotes his voice to shoutouts: Late-night wanderers, partygoers, newspaper deliverymen... cabdrivers... Good morning to ya. Listeners call in to request tracks, tell stories, or just say hello. Your ears are ringing and your friends have left and the drive-through is closed while they're changing over to breakfast, but the man inside your radio plays on in the electric dark.
