I see that we cross-posted there, more or less. Henry Burstow of Horsham in Sussex was a prolific singer, having a good 400 songs in his active repertoire at the age of 80. Several "collectors" noted songs from him, but that really only scratched the surface of what he knew. Vaughan Williams recorded him on wax cylinder at one point; sadly, the recording hasn't survived.

Henry was a boot-maker by trade; a singer and bell-ringer by inclination. He was an atheist and Darwinist, and, unusually for someone of his social position, published an autobiography (1912). Actually it was of the "as told to" kind; not that he wasn't perfectly literate in his own right. He was elderly and in poor health by then, though, and his friends sold the book by subscription to raise money to allow him to continue to live independently and not have to end his days in the Workhouse.

Not so long ago, it was the default assumption that songs treating sympathetically of Napoleon "must" have been Irish. That was to ignore the growing radical movement in Britain at the time of the Napoleonic wars, however. Many made the same mistake that Irish Republicans did; seeing Bonaparte as a force for revolution and freedom rather than for what he was; an imperialist exploiting revolutionary sentiment for his own ends. Some, like Frank Harte, still seem to be labouring under those same misapprehensions. Nevertheless, Napoleon (in the rosy afterglow of retrospect, and safely far away) does make a good romantic hero; and, like Julius Caesar or Tamburlaine, a fitting subject for tragic drama.

Henry Burstow was fond of "Napoleon" songs, and had a good stock of them; some are the only examples ever found with tunes. See other threads here, and DT files, deriving from -but not always credited to- his repertoire.
