Late on a weeknight it's dark and loud in Percy's Café Americana. A skinny, young white man mimics the smooth cries of Marvin Gaye's "Let's Get It On" like he just got off the bus from Motown, and every woman in the bar, young and old, is cheering him on. "With karaoke, everybody's a rock star," said Mark Ward, 22. After traipsing around the room with a wireless microphone and serenading a few strangers, he returns to a large table of his friends amid vigorous applause. "The thing with karaoke is everyone can do karaoke," he said. A singer in a local band, Ward's no stranger to the stage. But for most weeknight wailers, the sound system at the bar is probably the closest they will ever come to their own concert. It's music for the masses.
