That was enlightening, Susan -- thank you. I have seen that CD and thought to pick it up; having read your review, I think I'll do that.

When I was in the military I was stationed in Yorktown for a time, and spent a number of afternoons exploring the battlefield and learning the history. The ground has been marched over a number of times, not only during the Revolution, but also in the Civil War during McClellan's Peninsula campaign. The "World Turned Upside Down" legend is a good one, given the irony of the title, and may in fact be true. My guess is that, if the tune was a popular marching tune of the time, they probably played it, and a number of others, as the surrender ceremony was taking place. There were thousands of troops engaged in that battle, and it would have taken them a while to march by company to the field of surrender and stack their weapons. Wouldn't be surprised if a lot of tunes were played before the surrender ceremony concluded.
