As I suspected, the scene of dancing at Beirut airport, was not spontaneous. It was staged by an ad agency. Alain sent me this: "There is the discription of the video on the official page of Beirut Duty Free:
"Whilst the idea of a flash mob isn't a new thing, a Dabke / Hip-Hop flash mob in Beirut Rafic Hariri International Airport (Beirut Duty Free) at a time when the region is in flux is certainly a first. On March 5th, 2011, passengers experienced something a little different. A flash mob performed a mix of Dabke and hip-hop to entertain and delight passengers and airport staff alike. M&C Saatchi and Beirut Duty Free, created this vibrant event as part of their "Take Back More." campaign. The aim was to literally create a wonderful memory of Lebanon that passengers could take with them on their journey." So typical. And also typical, the event was not even original: Karim sent me this: "the above is nothing but a poor copy from T-Mobile work at Heathrow Airport and other stations in London tfaddal:"
