Agree,
As you eluded to, a large percentage of the PBM cast members were recruited from Pattaya. I've had the delight of being with a few of them back then.
One, named Moss, started off in training wheels working the little stage in Gentleman's Club - then sprouted a few underarm hairs and graduated to the stage at KAOS (Sunee) working under the tutelage of Beer and Mak before they drifted off to open Nice Boys..
He was, and may still be, one HOT number. I've seen him in several PBM movies but always under an alias.
His favorite line was "Up2U" and I never knew what to do first.
