Johnny was later replaced by Jimmy's brother, Lynn Fautheree; but the name of the duo did not change, as the producers feared a career slump. Lynn brought the group's style closer to rockabilly with songs such as "Sweet Love on My Mind," "What'cha Doin' to Me" and "Sweet Singing Daddy". They played with Faron Young's group, the Deputies, and sometimes on the Grand Ole Opry, in addition to continuing to appear regularly on Louisiana Hayride. The song was written by Geraldine "Jerry" Hamilton. Lynn Fautheree married Dianne Hamilton, Geraldines daughter. Lynn and Dianne left the music business soon after the birth of their daughter Lisa Fautheree in 1959. At the end of the 1950s, after the Fautherees moved back to Texas, Lynn exited and Mathis returned to the duo, and they recorded together until 1961. In 1995, Johnny & Jimmy reunited for the first time since 1961, and released the gospel single "It Won't Be Much Longer".
