Hmmm, I guess any high school band is free to file a copyright for their performance(s) as intellectual property (as they see fit), but this seems far more like games-[man/woman]-ship than anything else (see Marcus and/or L.D. Bell). If I'm not mistaken, Bowie uses, or at least used (last year), the same drill writer and/or music writer as some of the other bands in their 'geographical region' (Round Rock, for instance). These other bands don't seem to be nearly so constrained by, so called, copyright restrictions when posting videos of their drills/shows (some of these drills/shows have even made their way to bands outside the state of Texas, with corresponding YouTube videos currently available). Just sayin'....
The Austin American Statesman has an early version of the Bowie show on their 'Battle of the Bands' web section for 'week 1' of this year (vs. Westwood).

Also, here's Round Rock's 10-8-2011 performance at the Westlake Marching Festival, sans any apparent copyright restriction(s):
One is left to wonder whether Bowie, or any other "copyright sensitive" band, would pursue legal action if their drills/shows were legitimately recorded at a football game or competition, and subsequently posted by the person who recorded them?
These are high school marching band shows we're all talking about here; they're supposed to be fun for the students, the parents, and the competing bands. C'mon, let's get a grip.
