The 35-year-old actor and jazz musician is tapping into social networking on Facebook and Twitter to help organize a flash mob to converge on the Red Line during rush hour next Monday and break out into caroling. What are you organizing for next Monday evening?

This is something where we are gathering people together who want to make merry on the Metro system, which I feel like too often can be too drab especially during rush hour. And everyone loves this time of year and everyone loves to sing. It’s just going to be a lot of fun…We made this Facebook invite [Sunday] and it’s already kind of blown up.
