Have you ever imagined what it might be like to live in a musical-theater world, where ordinary people broke out into song on the street, backed up by passersby who happened to fall into tightly choreographed dance routines? This week, aspiring producer Ryan H. Mackey wants to gives you that experience via an ambitious project he calls Break Out in Song. Once a day for the rest of the week, an all-out production number will erupt in a public place, to the delight, Mackey hopes, of surprised spectators. “We’re on a mission to inspire future theater artists and audiences,” he says. “And maybe shake a few things up within the industry. Lord knows something interesting needs to happen.”

If the resulting numbers are anything like this famous clip of a similar stunt in Belgium—or this even more famous clip of Improv Everywhere’s more local disruption—then New York is in for a treat. Here’s the current schedule:

7/16/09: “If My Friends Could See Me Now,” Time Warner Center, 6pm
7/17/09: “Don’t Rain on My Parade,” South Street Seaport (Fulton and Front Street), 5:45pm
7/18/09: “Anything Goes,” Intrepid, 3pm
7/19/09: “Consider Yourself,” Times Square (in front of the Marquis), 1pm

If you do go to these places to check out the singing and dancing, try not to give away the game to spectators who might be surprised to discover that all the world can be a stage.
