Barbara Lynn (born Barbara Lynn Ozen, later Barbara Lynn Cumby 16 January 1942 in Beaumont, Texas) is an American rhythm and blues guitarist and singer.
She played piano as a child, but switched to guitar. Inspired by blues artists Guitar Slim and Jimmy Reed, and pop acts Elvis Presley and Brenda Lee, she created an all-female band, Bobbie Lynn and the Idols.
Singer Joe Barry introduced Lynn to producer Huey Meaux. Her first single "You'll Lose A Good Thing" was a #1 R&B hit and Top 10 pop hit in 1962 and was later a country hit for Freddy Fender.
Soon Lynn was touring with such soul music greats as Gladys Knight, Stevie Wonder, Smokey Robinson, Dionne Warwick, Jackie Wilson, Sam Cooke, Otis Redding, James Brown, Al Green, Carla Thomas, Marvin Gaye, Ike and Tina Turner, The Temptations, and B.B. King.
She appeared at the Apollo Theatre, twice on American Bandstand, and even had her song "Oh Baby (We've Got A Good Thing Goin')" recorded by The Rolling Stones.
She married for the first time at age 28 and had three children. While living in Los Angeles, occasionally appeared at local clubs. After her husband's death, she returned to Beaumont, where her mother lived, and began recording again.
