Performing on the Paris Metro

Here's a video from the New York Times about musicians playing on the metro.  http://nyti.ms/1fjwYSA  After three months, I still love taking the metro.  Everyone complains about it: it's crowded, dirty and bewildering.  But it beats the heck out of finding a parking spot.  And in a city crowded with cafés with outdoor tables where all the chairs are facing out for the purpose of people-watching, you can watch a heck of a lot more people in a short time on the metro.  They don't serve drinks, but, as the video shows, there is live music.
