Actually dancing in Twilight was not the norm in the 1980s. The bar had probably 60 - 80 boys with 40 or more on duty on a weekday evening and almost all at the weekends. The stage behind the bar was tiny and I never recall more than four being up there at any one time. Most boys knew they were there for one thing - to be offed or at least to get a drink or two, and so the nearest they came to dancing was an occasional soft shoe shuffle. Some were shy at being naked on stage and would cover their assets with their crunched up underwear. That is until one of the two mamasans would bark an order whereupon all was slowly revealed. Once they had done their bit on stage and on the mirrored pillar in the centre of the bar, they became far more friendly. Inviting one or more to have a drink, all their inhibitions disappeared.
The next four boys waiting to go on stage would be hunched down behind the bar desperately trying to work up even a mini erection. They always seemed to be laughing and enjoying themselves. But once on stage, quite a few just seemed to be embarrassed. This was so different from the much smaller Apollo Bar in Soi 4 where in the mid-1980s all the dancers did do a bit of dancing on the catwalk even when nude and all seemed to be having fun.
The only bar with real dancing was My Way off Rama 4. These boys were great, constantly smiling and almost all aggressively cute. The stage had two or three poles and most of the boys would use them to enhance their dancing feats. Barbiery was somewhat similar in terms of dancing, although in that bar it was the shows which were the main draw. Barbiery had nearly 100 boys at the weekends when the place would always be packed with as many seats as possible crammed in. The shows featured nudity and the boys always seemed to be having fun. I don't recall any of the boys revealing all in My Way.
