In a world being driven apart for political gain, choreographer Mark Haim wanted to make something joyous and humorous that brings people together. He asked 432 people from more than 20 countries for a video of them doing 5 to 10 seconds of movement. He chose dancers, students, friends, and relatives, some of whom he hadn't spoken to in years. The idea was to learn all their "dances" and perform them from oldest to youngest, becoming a single vessel for hundreds of different people. In the end, 371 people sent in videos. The dance has taken more than two years to learn. The show premieres on April 5. After his dance, the bar will open up and a postshow party will begin. Haim will play the sequence of video submissions on a big screen so the audience can see the hundreds of parts that made up his joyful sum. by Rich Smith
