From a 1959 film ‘Lan Aoud’ (I will not return لن أعود) which starred Kamal al Shinnawi.and Abdel Menam Ibrahim who are the two men entering the nightclub. Also starring were Soheir al Babli, Samira Ahmed and Abbas Fares.The lighting in the first clip is very dark and the dancer’s face is not visible but it *could* be Taheya Karioka who had a part in this film. I didn’t get the whole movie so I’m at a bit of a loss. The dancer in the second part of the clip is Fifi Salama and the music she’s dancing to is ‘Khatwit Habibi by Mohammed Abdel Wahab (thank you Amirah al Shuruq).
