Many years ago I saw a scene from a movie where a little boy was playing at some sort of outdoor piano concert, and a lady seated in the audience (the boys mother? ) began to sway and dance and eventually got up and continued moving towards the pond next to them and then right into the water... other people from the crowd got up and pulled her from the water and the boy stops playing the piano. I know it's vague... but I would appreciate any help in finding what movie this scene is from!
