I lived either close to or in NYC late 50s-early sixties. I remember in particular two Greek clubs that employed mostly young Egyptian girls as dancers. Port Said, and Egyptian Gardens. Some of the guys I got to know said they were as young as 16, but I am not sure. Some of them looked very young.
Here is Serena, from a clip in 1960, at Egyptian Gardens. The 2nd is Elena Lentini, 20 years later and still a very exciting dynamic dancer. Both these girls danced at Port Said, and Egyptian Gardens. There was one other club in the area that we went to, but I can't remember its name. This was exciting stuff for an 18 year old, made better by the NYC drinking age of 18. Ouzo makes you whoozo!
As i see it, this older style is more dynamic, more musically interesting, but perhaps less overtly sexual than the more recent dancers. These women are incredible athletes, as the dances might go on for 7-8 minutes, very fast. Then someone else for a dance, then she is back again. They couldn't get away with a just a few bumps and grinds.
