Gloranny Plenty of chicken for the plebs, because, as you said, you had them in your backyard, and so did we, and so did many others.
A celebration is a celebration whether a coronation or a wedding and, in our period, most weddings included a reception where parents would often spend money they had saved for decades, on a daughter's wedding, to make sure they 'did her proud'
I am sure you, of course, managed with a pie and a pint in a pub or even a cup of tea heated over a fire of scavenged twigs, but you have only to see the wedding photos in so many houses to realise that most people, pushed the boat out - and pride of place on the buffet table or served plate would be chicken.
