ORLANDO, Fla., Dec. 19 (UPI) -- The organizers of a seemingly spontaneous outbreak of singing at Orlando (Fla.) International Airport say plenty of planning went into the flash mob event.
About 120 people quietly gathered in the airport terminal late Saturday and, on cue, broke out in the Christmas classic Hallelujah chorus from Handel's "Messiah."
The Orlando Sentinel said Sunday the performance was a joint effort of the United Arts of Central Florida, who enlisted the cooperation of the airport management and the Transportation Security Administration well in advance.
"Don't just show up," said Margot Knight, president of the organization.
An undercover conductor was stationed on a second-floor balcony to lead the singing, which was received with a hearty round of applause from the scores of travelers who had been waiting for flights.
"We've done entertainment with the airport for 20 years," said Knight, who added Saturday was their first foray into flash mobs.
