Dottie West - very, very nice person, who treated everyone as if they had something important to say. Again, I was a teen, so this made a big impact.
Tommy Overstreet - at the time, "That's Where My Woman Begins" was big on the chart. He and his band were high energy, good humored, fun to work with.
Red Steward, Red Foley, the Collins Sisters. Seemed rather jaded and aloof to me.
My parents had a country music band. Mom had recorded some singles and an album, and was trying to break into the "big time". So, Dad worked with various promoters to bring in some of the big names, and our band was the opening act. A local group would sell tickets in exchange for the profits from the show. Most fun group were the square dancers, who arranged an after-show party at a local supper club for Tommy Overstreet and his band. Good times.
*Steward should be Stewart
