Thank you ClaireBear, I learn something here relatively often and that is one. I don't always trust Wikipedia, despite the fact that it is increasingly cited in US courts. It is not I think regarded as an academic source in either English or US universities.

Have you a date for "Hard Times"? if "Roast Beef" is 1731 and "Hard Times" is later that might be good.

Hogarth is good, since he lived on the Isle of Grain in what is now the Hogarth Arms and had one of his famour orgiastic weekends at the Nag's Head in Lower Stoke - but he is too early at 1748.

Many other good ideas and sources above. I will aim to do some research and revert. I found a prmising looking CD on Amazon as well - do I spring £15 on spec? Hmmm Hmmm.
