Western swing was extremely popular throughout the West in the years before World War II and blossomed on the West Coast during the war. In the 1940s, the Light Crust Doughboys' broadcasts went out over 170 radio stations in the South and Southwest, and were heard by millions of listeners. From 1934 to 1943, Bob Wills and the Texas Playboys played nightly at Cain's Ballroom in Tulsa, reaching crowds as large as 6,000 people. 50,000-watt radio station KVOO broadcast daily programs. Regular shows continued until 1958 with Johnnie Lee Wills as the bandleader. Doyle Brink and his Texas Swingsters out of Waco, Texas, also played on the road for almost 50 years.
