In 1970, Twitty recorded and released his biggest country hit, "Hello Darlin'", which spent four weeks at the top of the country chart and is one of Twitty's most recognized songs. In 1971, he released his first hit duet with Loretta Lynn, "After the Fire Is Gone". It was a success, and many more followed, including "Lead Me On" (1971), "Louisiana Woman, Mississippi Man" (1973), "As Soon As I Hang Up the Phone" (1974), "Feelins'" (1975), "I Still Believe in Waltzes", "I Can't Love You Enough", and many others. Together, Conway and Loretta (as they were known in their act), won four consecutive Country Music Association awards for vocal duo (1972–75) and a host of other duo and duet awards from other organizations throughout the 1970s.
