I think one good thing about all the background material was that it helped separate the activity from the high band stereotype.
I too wondered why the volunteers were not mentioned.
Random Question:
If a current drum corps was to change it's name and ideas to bring back an old corps, which one might it be and who would they bring back?
Many HS bands out there have done a good job using amps powered by car batteries. ( Just because I think they did a good job doesn't mean I support the use of amps )
