Subway drummer business model

If you've taken the subway in New York City, you've almost certainly seen a drummer.  Occasionally with an actual drum, as seen here.  More often with a 5 gallon plastic can.

One thing I've never seen is a drummer with an extra seat and an extra drum, offering to give lessons.  I'm not sure if this would generate more revenue, but if I were a subway drummer I'd try it.  For a tourist visiting New York City, it might be fun to have your friend take a video of you drumming alongside a real New Yorker.  Five dollars for a five-minute lesson might seem like a reasonable fee for the experience.  Get the spectators to participate in the experience.
