Uh, this DUmmie doesn't know squat. Reveille is played at flag raising, and Retreat is played at flag lowering. One can see the current list of bugle calls at United States Military Bugle Calls. Nowhere does the National Anthem appear on that list, nor do I ever recall it being a bugle call. Nor should it be. It's the Nation's Anthem, not a call used to announce events.
“Reveille is played at flag raising, and Retreat is played at flag lowering.”
Thank you. I was in a hurry this morning and did not make this point. In 25 years, I have yet to hear the Anthem as that DUmmie mentioned.
