Spring is in full bloom, and in New York that means pianos are popping up like wildflowers. Michelle Miller talks with the founders of Sing For Hope, a group that has placed hundreds of pianos at parks, gardens and street-corners all over the city. She also talks with "Late Show" bandleader Jon Batiste about his support for the program; and she visits P.S. 8 in Manhattan, when one of the pianos is being donated to aid their arts education.
