A wacky, wonderful underwater concert's happening this weekend in the lower keys.

   Not only will divers listen to music from speakers suspended from boats, there will be mermaids serenading them with underwater instruments.

    The 30th annual annual Lower Keys Underwater Music Festival's happening Saturday at the Florida Keys National Marine Sanctuary at Looe Key Reef, some six miles south of Big Pine Key.

   The concert's playlist ranges from ethereal New Age music to ocean-themed songs such as the Beatles' "Octopus's Garden." 

   The concert also has a serious side - promoting dive safety and protecting the reef.
