“Edit:Undo” is a 21st Century musical of, by, and for today’s digital-age teens. On a computer, you can fix your mistakes by clicking “Edit:Undo,” but, in life, things aren’t always that simple. Today’s young people are very busy in school, but feel a lot of stress and anxiety. To cope, and to make connections with friends, they use new high-tech tools they can’t live without, tools many adults don’t like and don’t understand. Cell phones, IM buddy lists, and other devices can make teenage life more enjoyable and manageable—but, sometimes, this virtual life can get in the way of real life.
