This is from the Christmas Revels, a show we put on every year in Boulder (with a different setting each year). There are nine Revels companies around the US (the first one started over thirty years ago in Cambridge, MA), each doing a different show, but they all end the first act with the Lord of the Dance, which ends with most of the cast dancing down from the stage into the audience, and getting audience members to dance through the aisles. I'm the stage director for our company (The Rocky Mountain Revels), and I also act in the bits that don't involve singing. This was from the dress rehearsal for this year's show.
