Sometimes fun to troll the Bodleian by date, but I often twist off. I entered 1812 and among other things some Christmas carols came up. Forgot all about what I was looking for. But one with the first lines "A kid of a booze staggering mien on a long-eared donkey came" perhaps was a tavern performer's song. "Wednesbury Concert" is amusing (Firth b 26(522). Of course not sure if these were performed in public, but they could have been.
Doesn't answer to the topic, however.
