The songs Cindy Walker wrote are so timeless, many have had multiple lives. The gut-wrenching “You Don’t Know Me,” a country classic for Eddy Arnold, was crucial to Ray Charles’ game-changing R&B/country crossover. The honky-tonking “I Don’t Care” was a smash in the ’50s for Webb Pierce and in the ’80s for Ricky Skaggs. And after Roy Orbison made the lustful “Dream Baby” a ’60s rock standard, Glen Campbell gave it a country makeover in the ’70s.
