From the local newspaper: "Due to the impending weather for Saturday, the following change has been made to the schedule: Sadie Street Singers will now perform at 8:30 pm Friday. Saturday's schedule has now changed from 9:30 a.m.-2 p.m." I checked the Anamosa booster website but they do not seem to have a specific schedule up.
With no finals at a bunch of places, it seems that the general consensus is to just go 4A/3A/2A/1A, like what Des Moines Christian did last weekend. I believe Marion might be a 3A school competing up? but to answer your question, I believe it is just divisional awards.
Attending choirs are listed. It was also shared that Xavier will be attending virtually via video submission, the remaining choirs will perform in-person.
