There is no need for them to take them off, they are AMAZING. It is incredible that they can do a whole show with them. Also, it's not the choir's or schools' fault, it's Dane County trying to keep them safe.
It’s not “tyranny” or ridiculous to have performing singer/dancers to mask up. Most of my groups this year have performed with masks on for the safety of the choir as a whole and the audience, as well as to ensure they are able to have a full, normal (as normal as possible) season amidst the COVID-19 pandemic. I applaud directors/public health officials who are making choices that put the health and well-being of their students first, even if it might hinder their sound. I love show choir as much as the rest of y’all, but it is not more important than the health of these kids.
