The song features a solos by washboard, banjo, scat vocal, kazoo, and washtub bass. The bathroom featured one toilet, one shower, a washboard and a washtub. It includes both banjo and gut bucket (washtub bass) players plus a Band Auxiliary. I on harmonica and Alfred Elkins on imitation bass (possibly a washtub bass). Her first patent combined a sink and a washtub. Just a window in a wall where they sold meat from a washtub. This unintentionally drew attention to Operation WASHTUB. From there, I was promoted to the washtub.
