Since this seems to be a re-enactment thread, I might as well add my own background. I'm ex-Napoleonic Association (63rd Foot and the 2nd Silesians), ex-ECWS (Sir Thos.Blackwell's) and now Great War Society (Middlesex Regt) - well I have been doing this game for 25 years - Its surprising how many societies have "drinkin' and singin'" units. For those not in re-enactment, there is no sight quite as surreal as a mass of re-enactors from different periods involved in a mass singing session (for those in the hobby, remember Kirby Hall I?) Just rabbiting (sorry, Wilfreding) on.
