Do you know people that would be up for this, maybe as a contest?
we could have prizes, we could have in-person concerts with multiple groups, we could generate lots of open/free music.
We would bring 100 year old music to a new audiences. We might be a bunch of people singing.
I would really like to hear shape-note singing like they do at Bread and Puppet.
