James Robert Wills was an American Western swing musician, songwriter, and bandleader. Considered by music authorities as the founder of Western swing, he was known widely as the King of Western Swing. He was also noted for punctuating his music with his trademark "ah-haa" calls. Wills formed several bands and played radio stations around the South and West until he formed the Texas Playboys in 1934 with Wills on fiddle, Tommy Duncan on piano and vocals, rhythm guitarist June Whalin, tenor banjoist Johnnie Lee Wills, and Kermit Whalin who played steel guitar and bass. Oklahoma guitar player Eldon Shamblin joined the band in 1937 bringing jazzy influence and arrangements. The band played regularly on Tulsa, Oklahoma, radio station KVOO and added Leon McAuliffe on steel guitar, pianist Al Stricklin, drummer Smokey Dacus, and a horn section that expanded the band's sound. Wills favored jazz-like arrangements and the band found national popularity into the 1940s with such hits as "Steel Guitar Rag", "San Antonio Rose", "Smoke on the Water", "Stars and Stripes on Iwo Jima", and "New Spanish Two Step".
