Following their 1957 breakup, Armstrong joined Hank Thompson's Brazos Valley Boys for six months. Road life finally exhausted him and he quit, returned to L.A., and joined Cliffie Stone's Hometown Jamboree and then Tex Williams' band. He released two singles, Gloria and If You Leave While I'm Sleeping, in 1959. In 1965, Armstrong won his first ACM Fiddler of the Year award and also released the single The Orange Blossom Special. He then played with Gene Davis on the television series #Star Route before joining the Sons of the Pioneers in 1966, with whom he sang lead and alternating tenor. He stayed with the Pioneers until early 1972, when he joined the Chaparral Brothers. During the 1970s, Armstrong also had a solo recording career, which produced three albums. ~ Sandra Brennan, Rovi
