Can foreign tourists see Pakistani dancing girls?

I heard about dancing girls of the Swat valley, Pakistan, as a result of news articles about attempts to eliminate them. For example, Dancing girls of Swat back in business.

I haven't been able to find out much about them - I don't even know what word residents of the Swat valley themselves would use for them. Currently, I'm trying to work out if it's even possible for foreign tourists to see them.

First, is it legal to see dancing girls?

Secondly, some articles have stated that you need a reference in order to be a guest.

“There are 10 to 12 dancing girls in this street. Strangers are not allowed to come here. You can only come through a reference,” says Shabana.

Is this a matter of prestige, trying to make the experience more exclusive? Or is it more a matter of safety, and knowing that the customers won't behave inappropriately towards them? I'm asking because if it's the latter, then it may be possible to get a reference, whereas if it's the former, then it may not be possible to get a reference.
