BIG PINE KEY, Fla. (AP) - Divers and snorkelers are getting the chance to listen to a radio station's broadcast while underwater.
More than 500 divers and snorkelers descended in the Florida Keys National Marine Sanctuary Saturday at Looe Key Reef for the quirky Lower Keys Underwater Music Festival. The festival offers an offbeat salute to rock with divers costumed as "Eel-vis Presley," ''Bob "Marlin," ''Joss "Stone Crab" and other famed musicians.
The specially programmed subsea concert features music such as the "Theme from the Little Mermaid" and "Octopus' Garden," selected for tunes that sound good underwater.
The festival also has a serious side. Interspersed between music for the four-hour concert are public service announcements produced in conjunction with officials at the sanctuary to promote coral reef preservation.
