Loretta Lynn is a classic country singer whose life--from her autobiography, Coal Miner's Daughter--is a well-known story. She was one of the first stars to sing with a feminist point of view. Her songs, like "Don't Come Home a-Drinkin' (with Lovin' on Your Mind)" and "The Pill," broke new ground in country music. Lynn (b. 1935) and Conway Twitty were named Vocal Duo of the Year by the Country Music Association for years in a row in the early 1970s.
