Just FYI, I am NOT a current student at Coppell...I am a marching tech. The students have not been told anything that I'm aware of (I have a sister in band). There are 370 students enrolled in band, but only 270 will be marching. I do not know if the 270 includes colorguard, drumline, etc or whether it includes everybody.
...and good luck trying to look up the show information on a website or asking parents. Most of the band booster parents don't even know what the show is yet.
The directors and visual, music staff are talking every week and already making some changes to the program.
