A troupe of dancers performing to the song ‘Aziza’ written by Mohamed Abdel Wahab.  This is a scene from the 1965 film ‘Oriental Nights’ (Layali al sharq). The film is set in Lebanon and stars many famous Lebanese actors and dancers including Wadi al Safi, Sabah, Nadia Gamal and Nasri Shamseddine.
Bizarrely, at the conclusion of ‘Aziza’, they dance to a piece of classical music, is it something by Rimsky-Korsakov maybe?
