Midway through the hour, the screen dipped to a studio that couldn't be a studio: tables welded from shopping carts, lights scavenged from salon mirrors, microphones made of rolled magazine pages. The host stood in front of a green door with spray paint that spelled UPD in sloppy block letters. He leaned on a broom like a troubadour and introduced a guest: an ex-delivery driver who now ran a clandestine repair clinic in a subway stairwell. He had fixed a turntable for a kid who couldn't afford music lessons and a prosthetic foot for a dancer who'd lost hers to a misstep and a bad night.
