The Underwater Music Festival had a brush with the King of Rock and Roll when an Elvis impersonator was among the snorkelers and divers who swam Looe Key Reef.

Neil Goldberg, of Key West, dressed in a white-caped jumpsuit and flashy gold chains, joined several hundred visitors and residents who took the plunge for the six-hour weekend radio broadcast.

"We even had a Chihuahua in goggles and a swim vest on one of the dive boats," festival founder Bill Becker told the Associated Press.

Other participants dressed as a mermaid with a blue and purple tail and a hot-pink angelfish with gauzy fins, while an underwater band pretended to play instruments sculpted to resemble deep-sea creatures.

The broadcast featured melodies ranging from Jimmy Buffett's "Fins" and the Beatles' "Yellow Submarine" to classic Presley hits.

The songs were mixed with public service announcements promoting reef preservation and warning divers to avoid touching the coral.
