Conway Twitty & Loretta Lynn

In 1971, Conway Twitty and Loretta Lynn began a professional partnership. As a duo, Lynn and Twitty had five consecutive Number 1 hits between 1971 and 1975: "After the Fire Is Gone" (1971), "Lead Me On" (1971), "Lousiana Woman, Mississippi Man" (1973), "As Soon as I Hang Up the Phone" (1974), and "Feelins'" (1974). The hit-streak kick-started what would become one of the most successful duos of country history. For four consecutive years (1972–1975), Lynn and Twitty were named the "Vocal Duo of the Year" by the Country Music Association. In addition to their five Number 1 singles, they had seven other Top 10 hits between 1976 and 1981.
