Larry Spud and His Idaho Potatoes

Band that plays "The French Fry Blues" (hmm, sensing a theme here) during a USO show in the "Oh How We Met the Night We Danced" episode of The Dick Van Dyke Show (first aired 31 Oct. 1961). We don't really hear the band (a trio of guitar, clarinet, and standup bass), but they sound kind of jazzy.
