There are plenty of things you might expect to find a jazz legend such as Herbie Hancock doing with his time -- flying to concerts in Europe perhaps, or preparing for a jazz festival in North America, composing new songs, maybe even catching a break from his hectic schedule.

Playing piano with hopeful young musicians at a senior high school in Tokyo is perhaps not one of them.

But that is exactly what he was doing one afternoon early this month when he shared a stage with musically minded students at the American School in Japan. As they worked their way through jazz classics in an hourlong workshop, the students, some looking a little nervous, a few of them tackling their parts with confidence, were clearly enjoying this rare opportunity.
