"Levee Dance" by Florence Price (1887-1953) is actually a piano piece. But it works quite well on the organ, with a few tiny adaptions. I wish the rattling of the pedal action would've been less but when playing older instruments, you don't always get what you wish for ;-) You can also see that I would've needed a third hand for the stop changes. Anyway, it's a lovely and fun piece and if you would like to play it yourselves, you can find the sheet music on IMSLP: https://imslp.org/wiki/Levee_Dance_(Price%2C_Florence)
