Everyone's favorite "coal miner's daughter" joined the Opry after getting married, having four kids, and signing a recording contract -- all before age 25. Lynn and her husband, Mooney, distributed (largely by hand) her first single, "I'm a Honky Tonk Girl," and through word of mouth and steady airplay, the single reached number 14 on the country charts in 1960.
That impressive debut got Lynn her first appearance at the Opry that year, which boosted her career to the next level. She would go on to have dozens of megahits by blending her country girl image with some potent subject matter, such as birth control and deadbeat husbands. Coal Miner's Daughter, Lynn's autobiography, was made into an Academy Award-winning movie in 1980.
