Can dance reduce people to tears?

I've just had a flyer for a Chinese dance performance. It informs me that if I attend, I will be deeply moved - very probably to tears.

I have two left feet, and no sense of the beauty of dance, so perhaps one of my more enlightened friends can enlighten me:

1. Is it actually possible to be reduced to tears by watching dance?

2. Would I be allowed to sue the company if I went, and didn't cry?
