Back in the day many jananis didn't used to dance - my mum and her sister are terrible at dancing and when I was younger I would ask why they didn't dance like other ladies, and instead just stood there, did the mandatory clapping, and swiftly leave. I remember asking my Bibi about this too. According to them the "upper castes" did not engage in this behaviour; it was not permitted and seen as besharmi. However certain castes were permitted, and so dancers were hired I think? Can't remember.
Ironic now though. You see women who are well past the age of wearing brightly coloured suits nach'ing and tapp'ing. Oh vi uchi jaat de.
Weddings were so simple. Close family would go for Anand Kaaraj, everybody went back to the house, fed the baraat, sagan, bas. Hun pura drama hunda ah.
The suggestive dancing has gone on for decades.
The first time I saw it, my jaw dropped. In Punjab nobody bats an eyelid.
Compared to Punjab, you will probably see more people in the UK going to Anand Karaj and that I'd probably because of the milni and tea at the Gurdwara whereas the milni and tea in Punjab is at the palace.
Never underestimate the lure of free food.
