fairly sure i first heard this on radio but may have been tv, circa early 80's and am fairly certain it was Spike Milligan reciting, which would match with it being radio and the era, so I always assumed it was his own, the usual irreverent frivolity we know and loved him for. It was a rhythmic chant, poetry-like but no tune that I recall. It's a bit vulgar for her but close your eyes and pretend that it's Pam Ayres reciting, that would be funny, with the broad accent of hers.... where is she now....
