My God, the stuff you can find on the internet!
For some reason the words 'a gentleman dapper stepped out of the crapper' have been going around in my head but I couldn't remember anything else so I googled it. Of course I did. I was in Australia in 1961-62 with the Royal Air Force and bought a book of comic verse. This was one of them. I had no idea that it was a song. Thanks very much. I recall there was another poem about a dog with sugar diabetes. Anyone?
