Watch the amazing verbal choreography behind Grease Live

The Verge:

…this video from the show’s associate director Carrie Havel shows you a small slice of the action, with Havel coordinating the live footage — singing along to “Great Lightning,” but with all the lyrics replaced with camera numbers.

It just goes to show that when it comes to live performances, the choreography behind the scenes is usually as impressive as what’s on stage.

This behind the scenes stuff is fascinating. You can’t begin to imagine the work that goes into a production like this and then to add to the pressure, they’re doing it live. Incredible work.
