Johnny Cash soaked up sounds from across the American musical map. The heavenly gospel harmonies of The Swan Silvertones' “Four and Twenty Elders”; the unapologetic rockabilly of “Move It On Over,” Hank Williams' tale of a rounder who literally ends up in the doghouse; and the resigned blues of Woody Guthrie's drifter's anthem “I Ain't Got No Home In This World Anymore” all seeped into Cash's veins.
