Six degrees of Kevin Bacon? The boy's got nothing on Delbert McClinton. The Texas native got his chops in a Blues house band that played behind Howlin' Wolf, Sonny Boy Williamson and Jimmy Reed, then played harmonica in the early '60s for Bruce Channel and gave harp lessons to John Lennon backstage during Channel's UK tour.
