In 1995, the year of my first visit, dancing was the norm in all the go-go bars I visited and I can assure you that I visited a hell of a lot- though not Twilight- in Chiangmai, Patong, Bangkok and Pattaya. . Even the very small ones like Superboys (Patong) and Moonlight (Pattaya) had small dancing areas for three at a time.
Dancing of various levels of enthusiasm continued for another ten tears or so, as I previously mentioned.
I cannot recall any where the guys stood around and posed as they do now.
