At the Stratford Festival of Canada a few years ago they did "Inherit the Wind" in much the same manner, with lots of singing, hymns mostly, nicely harmonized, no instruments. It was more than atmospheric; it suggested that these dour, narrow-minded townsfolk actually found joy in something--their religion. It suggested further that harmony has something in common with comformity: like minds lead to happy results. That's what I wrote in my review, anyway, and it certainly deepend the play's meaning for me.
