"Can we sing a song of peace in a world that's full of fear?"

Although the words may sound like the kind of chant heard at antiwar rallies worldwide over the past few weeks, they are in fact part of a song in a musical that will be performed next week in Tokyo.

Han Chu Son, the South Korean director of "A Common Beat," hopes to send a message of peace to the world through the performance, believing that the common beating of hearts has the power to connect people of different backgrounds.
