Karl & Harty are more important for their influence over other groups such as the Blue Sky Boys and the Everly Brothers (who recorded their "I'm Just Here To Get My Baby Out of Jail") than their own career. Though not related, Karl & Harty were a psuedo brother act, performing regularly on Chicago's National Barn Dance in the ‘30s. The performances led to a recording contract with the American Record Corporation, where Karl penned his best work including "I'm Just Here" and "Kentucky," a beautiful ode to his home state. The duo later recorded for Capitol in the late '40s but soon retired from music not long after. ~ Steve Kurutz, All Music Guide
