Also, I realized that I have no idea why they play bagpipes during memorial services and googled it. One of the links offered the following:
"They sound right for the occasion. Bagpipes seem to have become associated with U.S. military, police, and firefighter memorial services on account of their connection with Scottish martial history. As early as the 14th century, Scottish warriors used musical instruments—mostly horns—to intimidate their English adversaries. (Indeed, contemporary accounts suggest that every Scottish knight carried a horn around his neck.) But it's not clear why this Scottish tradition in particular might have caught on among the U.S. armed forces while others have not. (You rarely see tartan-clad Army rangers, for example.) Perhaps the popularity of bagpipes at funerals is simply a matter of aesthetics."
If *you* happen to know the historical tie between US military and bagpipes, leave it in a comment, I'd like to know.
