Liturgical dance?

I first saw liturgical dance when I was 18 at Manchester College.  It didn't impress me then, and still doesn't.  But at least it was school girls then and they didn't dress in their underwear.  I've seen a number of suggestions for what this might be trying to say, but I wish I could see the expressions on these older men's faces (Metro New York ELCA [Lutheran]  Synod) in the audience.  Perhaps I've misinterpreted this and someone can clarify.
