An early black string band, the Dallas String Band with Coley Jones, recorded the song "Hokum Blues" on December 8, 1928, in Dallas, Texas, featuring mandolin instrumentation. They have been identified both as proto bluesmen and as an early Texas country band and were likely to have been selling to both black and white audiences. Blind Lemon Jefferson and T-Bone Walker played in the Dallas String Band at various times. Milton Brown and his Musical Brownies, the seminal white Texas swing band, recorded a hokum tune with scat lyrics in the early 1930s, "Garbage Man Blues", which was originally known by the title the jazz composer Luis Russell gave it, "The Call of the Freaks". Bob Wills, who had performed in blackface as a young man, liberally used comic asides, whoops, and jive talk when directing his famous Texas Playboys. The Hoosier Hot Shots, Bob Skyles and the Skyrockets, and other novelty song artists concentrated on the comedic aspects, but for many up-and-coming white country musicians, like Emmett Miller, Clayton McMichen and Jimmie Rodgers, the ribald lyrics were beside the point. Hokum for these white rounders in the South and Southwest was synonymous with jazz, and the "hot" syncopations and blue notes were a naughty pleasure in themselves. The lap steel guitar player Cliff Carlisle, who was half of another "brother duet", is credited with refining the blue yodel song style after Jimmie Rodgers became the first country music superstar by recording over a dozen blue yodels. Carlisle wrote and recorded many hokum tunes and gave them titles such as "Tom Cat Blues", "Shanghai Rooster Yodel" and "That Nasty Swing". He marketed himself as a "hillbilly", a "cowboy", a "Hawaiian" or a "straight" bluesman (meaning presumably, black), depending on the audience for whom he was playing and where he played.
