Songwriters seem to flourish on the fertile Oklahoma plains. Woody Guthrie, Roger Miller, Leon Russell, J.J. Cale and Jimmy Webb. Add Verlon Thompson to that list. Thirty years as a professional songwriter and traveling troubadour serve as credentials. As a solo performer, and as the trusted sidekick of Texas Americana songwriting icon Guy Clark, Verlon has viewed the world from stages everywhere from Barcelona to Binger (his hometown in Oklahoma).
