"12th Street Rag" was composed by Sage Guyton and Jeremy Wakefield (and Nicolas Carr in "12th Street Rag with Bass"). It features a ukulele, a bass, and a steel guitar playing. It is an arrangement of "Twelfth Street Rag," which was originally composed by Euday L. Bowman in 1914. There are two other arrangements, one being unused. It usually plays when something silly happens.
