Everybody knows Nashville legend Barbra Mandrell has country cred galore, as laid out on her massive 1981 hit “I Was Country When Country Wasn’t Cool.” But as early as the ’70s, she was giving Captain & Tennille a run for their money with the bouncy pop hooks of “Sleeping Single In A Double Bed” and flexing her R&B muscles on twang-tinged updates of soul gems like “(If Loving You Is Wrong) I Don’t Want To Be Right” and “Do Right Woman, Do Right Man.” Meanwhile, both “The Midnight Oil” and her cover of Shirley Brown’s Stax track “Woman To Woman” underline a knack for unapologetic cheating songs that’s country all over.
