"Twelfth Street Rag" was composed by Euday L. Bowman originally in 1914. The new version was composed by Sage Guyton and Jeremy Wakefield in 1999 for SpongeBob SquarePants, and features a ukulele and steel guitar playing and occasionally a bass. Two versions of this classic rag are used on the show, one recorded specifically for the show, one prerecorded version, and one that has yet to be used. It usually plays when something weird or crazy might happen.
