While I understand that getting the band out there performing is important, I made it very clear to my admin that pep rallies are part of what we do during our marching season. We do not perform in pep rallies after marching season ends. I put it to them this way:

"Pep rally season has ended. Those instruments are packed away in storage until the summer. We are now in 'concert season'. Asking us to perform in a pep rally at this point would be like asking the football team to get together to play a game while those kids are in the middle of basketball season. It is not appropriate at this time for the band to play that style at this point in the year."
