Jazz Jam session

Ann and I walked all over Paris Saturday, and decided to try a couple of concerts today!  Just chanced upon this "Vocal Jazz" at a place called Le Baiser Salé (the salty kiss!) on the rue des Lombards,  street known for its  jazz clubs.  These 3 musicians accompanied people who came to the club and wanted to sing.  The singers  provided a sheet of music, and the musicians accompanied them.  All off the cuff, very spontaneous.  Some of them better than others, but all very enthousiastic in front of a small but supportive group.  Totally novel experience for me, and fascinating! (Don't worry, Ann and I didn't sing!)
