Cool concept, Susan. Now, how can you best take it on the road? Reminds me, in a way, of the old time medicine shows, where the folks would bring the entire package into a small town and get everyone involved.Do you have a lot of unpitched percussion instuments for you audience (kids and adults) to play? There are also a lot of Orff type instruments that are played with just a little instruction, such as metalaphones, glockenspiels, zylaphones, etc. where bars can be removed to heep the folks in the right key. Get a few of those things going with what you allready are doing and, band, instant (or close to it) audience participation... Even lap dulcimers are relatively easy to play basic stuff.
Just ideas.
