Sweet Corner Symphonywas a doo-wop a cappella concert with amazing singing by Vincent Robinson, Ed Battle, Ken Parks, Dwayne Carrington and Hugo Jon Sayles. "Swanee" got the group's own satiric spin, and they also performed dozens of lesser-known songs. Ken Parks was mesmerizing as the ringleader: tall and heavyset in a gold-and-black dashiki, deploying his strong, mellow, expressive voice, shaking his head, gesturing, constantly on the move. Carrington provided powerful support with his bass baritone, and Hugo Sayles offered up a terrific falsetto. Vince Robinson radiated rhythmic good humor, and Ed Battle -- another knock-out performer -- had a couple of moving solos, including a version of the Lord's Prayer.
