My dad was the country music fan. He grew up in Shenandoah, Pennsylvania, birthplace of the Dorsey Bros. But all his buddies liked hillbilly music. One had a National lap steel with a cast iron body! You could pick up WWVA from Wheeling WV, even on the Philly side of PA. And WSN too. And I think alot of GIs from WWII got exposed to country music in the Army. He referred to steel guitar as "Hawaiian guitar." Old school!
