Answer by taking a quote from the following article:

Alvis Edgar "Buck" Owens Jr. (August 12, 1929 - March 25, 2006) was an American musician, singer, songwriter and band leader who had 21 No. 1 hits on the Billboard country music charts with his band the Buckaroos. They pioneered what came to be called the Bakersfield sound, a reference to Bakersfield, California, the city Owens called home and from which he drew inspiration for what he preferred to call American music. While Owens originally used fiddle and retained pedal steel guitar into the 1970s, his sound on records and onstage was always more stripped-down and elemental. His signature style was based on simple storylines, infectious choruses, a twangy electric guitar, an insistent rhythm supplied by a drum track placed forward in the mix, and high two-part harmonies featuring Owens and his guitarist Don Rich.

Owens co-hosted a radio show called Buck and Britt in 1945. In the late 1940s he became a truck driver and drove through the San Joaquin Valley of California. He was impressed by Bakersfield, where he and his wife settled in 1951. Soon, Owens was frequently traveling to Hollywood for session recording jobs at Capitol Records, playing backup for Tennessee Ernie Ford, Wanda Jackson, Tommy Collins, Tommy Duncan, and many others.  Owens recorded a rockabilly record called "Hot Dog" for the Pep label, using the pseudonym Corky Jones because he did not want the fact he recorded a rock n' roll tune to hurt his country music career. Sometime in the 1950s, he lived with his second wife and children in Fife, Washington, where he sang with the Dusty Rhodes band.  In 1958 Owens met Don Rich in Steve's Gay 90's restaurant in South Tacoma, Washington. Owens had observed one of Rich's shows, and immediately went to speak with him. Rich started to play fiddle with Owens at local venues. They were featured on the weekly BAR-K Jamboree on KTNT-TV 11. Owens' career took off in 1959, when his song "Second Fiddle" hit No. 24 on the Billboard country chart. Soon after, "Under Your Spell Again" made it to No. 4 on the charts and Capitol Records wanted Owens to return to Bakersfield, California.  Owens tried to convince Rich to go with him to Bakersfield, but to no avail. Rich opted to go to Centralia College so that he could become a music teacher while tutoring and playing local venues, but after a year of college, he decided to drop out and join Owens in Bakersfield in December 1960.  "Above and Beyond" hit No. 3. On April 2, 1960 he performed the song on ABC-TV's Ozark Jubilee.

Did he release any hits during his early years?
Above and Beyond" hit No. 3.
