You know, everyone that says corps can't be define isn't reading into the noun which is the name we all read. Drun and Bugle Corps. The groups have certainly changed. I still want to see only raw talent and what the kids are actually doing on the field. Once you change the composition, it inherantly isn't the same. Bugles will always be bugles, drums, drums, and guard has always been a part of the pagentry because of the military presentation of colors. Saxophones, clarinets, cellos, etc aren't the composition of the title. I find it intriguing that the USMC has moved backwards to try and maintain the origins of drum corps.
