.... a photo of Paul with some others in a street called Boogie St, does anyone recall this?
If you want to do some digging it's Bugis Street. Then again, maybe not. This from Wiki.
One of the "hallowed traditions" bestowed upon Bugis Steet by sojourning sailors (usually from Britain, Australia and New Zealand), was the ritualistic "Dance Of The Flaming Arseholes" on top of the infamous toilet's roof. Compatriots on the ground would chant the signature "Haul 'em down you Zulu Warrior" song whilst the matelots performed their act.
Over the years this became almost a mandatory exercise and although it may seem to many to be a gross act of indecency, it was generally well received by the sometimes up to hundreds of tourists and locals. The Kai Tais or Beanie Boys, as the transwomen were referred to by Anglophone white visitors, certainly did not mind either. By the mid-70s Singapore started a crackdown on this type of lewd behaviour and sailors were arrested at gunpoint by the local authorities for upholding the tradition. By this time those sailors brave enough to try it were dealt with severely and even shipped home in disgrace.
