In 1933 he moved back to Austin and began working at a Gulf service station on North Lamar Boulevard. In December when
Prohibition ended Threadgill bought the establishment, secured the first post-Prohibition beer license in Austin and opened it as Threadgill's Tavern. Threadgill and his wife, Mildred (Greer), ran the restaurant and tavern until
World War II, when they closed for a few years. While Threadgill worked as a welder for the war effort, the music did not totally stop. When
Hank Williams came through Austin and did a show at the Dessau Dance Hall, northeast of Austin, Threadgill was there. Hank was late, so Kenneth took the stage and was singing "
Lovesick Blues" when Hank arrived. Hank came onstage and finished the show. By the mid forties Threadgill was selling soft drinks and beer while his friends played and sang hillbilly blues. In the mid fifties groups of local musicians were coming every week to play, and Threadgill would pay them with two rounds of free beer. In the beginning there was no stage and performers played right sitting amongst the customers. "A microphone connected to little amp would be passed around to performers. Eventually Threadgill install a sound system and musicians would wait in the back for their turn. ==Post World War II & Janis Joplin==
