Eunice Campbell Morrison was a talented alto singer as a teenager traveling and singing with her father and brothers in the Campbell family through the oft-remembered singing convention period of the 1930’s. John and Eunice met at a gospel singing convention in Splendora, Texas in 1940. Eunice’s father, Carroll Campbell, immediately put John in the family quartet with Eunice to sing lead. They continued to sing together for over five decades and their talented children, Kent and Saundra, developed a great appreciation for Southern Gospel Music. In 1964, John opened the The East Texas Jamboree at Johnny Morrison’s Haybarn in Shepherd, Texas. This was a stage show for family entertainment that featured famous Bluegrass and Country artists from that era such as Ernest Tubb, Bill Monroe, Loretta Lynn, Barbara Mandrell and Bob Wills.
