I read a memorable story about Burl Ives pulling a group of people waiting in a theater into an amazing chorus. He had them sing, as a round, an old song many know, I learned it from a German student:

Himmel und Erde mussen vergehen,
aber die musica, aber die musica,
aber die musica, bleibet verstehen.

(which means heaven and earth must fade away, but the music, the music, the music, will remain.)

It's a great song. I don't know if there are verses or not.
