This is Egyptian bellydance legend Mona al Said in a performance filmed at the now defunct Omar Khayyam nightclub in Regent Street, London, sometime in the 1970s. Though born in Egypt, Mona moved to Lebanon to avoid the anger of her family at her decision to become a professional dancer. It was in Lebanon that she first became well known.
The 1970s were a golden time for Arabic nightclubs both in the ME and in the UK. Beirut was known as 'Paris of the Mediterranean' and if you've ever been to Byblos in Lebanon you will no doubt have heard the stories and seen the photos of the Hollywood 'names' who used to bring their huge boats into the harbour and then while away the evenings at the harbourside restaurants. When Lebanon plunged into civil war in 1975 many musicians, dancers and clients relocated to the UK. Visitors from the Gulf no longer went to Lebanon, they went to London instead. Asmahan of London writes an interesting piece in the Golden Serpent telling of her days as a dancer at the Omar Khayyam in its heyday.
Trivia: Unfortunately the Omar Khayyam club in London is often remembered for the bomb that was found there hidden under a seat back in 1984.
