I see you are well on form Alan. I new Darlinghurst was another Sydney suburb, but I was not aware of the gaol. Is that history, or just another part of the culture I missed when I was in Sydney. Has anyone pointed out that the reference to learning to swim, with the location of Wooloomooloo, would mean being thown into Sydney harbour.
And you have not made any mention of other sets of words that share the same tune, isn't there one that starts something like " Oh me name is ugly Dave .....".
