This is Egyptian bellydancer Hanan. Unfortunately the tape is very old and the conversion to a mpg is a bit blurred but its worth watching for her technique and dynamic shimmies.
The dancer in this scene is Hanan a popular Egyptian bellydancer from the 70s (not to be confused with actress and former ballerina Hanan Turk). The music is ‘Fi youm wa leyla’ (A day and a night) originally sung by Warda Al Jazairia.
This scene is taken from the 1979 film ‘Khalli Balak Min Geranak’ (Watch out for your neighbours) which starred Adel Imam and Lebleba playing newly weds Ahmed and Nawal. The couple move into a new apartment only to find that they have to share it with their eccentric painter neighbour Abdelsalam played by Fuad el Mohandes. Happy ending (eventually) as Abdelsalam meets Nawal’s mum Fawzia played by Madiha Yosri, falls in love with her and they get married.
The film also starred comedian Wahid Seif who died in 2013 aged 74 after a long theatre and film career.
