The blues bug bit Henry Cooper hard when he was 16. At the time, he was toiling as a busboy in an Oregon hotel. Paul Butterfield's "The Work Song" came on the radio, and that was it for the blues-struck teenager. He was hooked. Wasting no time, he headed out to buy records that would give him more of that bowled-over feeling he got while listening to Butterfield's band glide through the airwaves. Among his first purchases was a record that featured Muddy Waters and Butterfield, "Fathers & Sons." He also started frequenting blues clubs around the city of Eugene, where he discovered such harmonica players as Curtis Salgado, Mike Mother, and Bill Rhoades. Three years later, Cooper played the harmonica on a 45, and it was his first foray into the world of recording.
