The singing duo of Maurice Hayes and his 12-year-old daughter, Shanice, have become a popular attraction at the County Club Plaza since setting up on the sidewalk outside McCormick & Schmick's last Thanksgiving. Using backing tracks, they perform two sets on Friday and Saturday nights when the weather and their schedules allow. The elder Hayes is an accomplished performer, having graduated from the Armed Forces School of Music. Shanice Hayes was playing violin on the Plaza with her older brother, Shaheed, a sax man, when she asked her father to put together a list of songs they could sing. With material ranging from big band to country to R&B to misty-eyed classics such as "What a Wonderful World," the act draws crowds in the hundreds, and the gig has led to several bookings at weddings. Hayes pre says people frequently ask when they'll see Shanice on American Idol. "She loves going out there and performing," he says. We love to hear them both.
