What is clear is that a lot of these people who embrace Arab dance are NOT Arabic.
The was done at a Syrian-Lebanese Restaurant in a shopping mall/theme park called Barra World (World Bar), in Rio de Janeiro. The Mall has streets with recreations of architecture from around the world. It was designed to look like Epcot Center.
Interestingly the entrepeneur who built the shopping mall/theme park is Joseph Koury. K(h)oury is Arabic for priest, indicating he was probably of Arabic Christian ancestry.
It seems to be a weekly show, performed every Saturday.
If you are in Rio, look it up.
