I guess it is hard to find something that rhymes with Yom Kippur and make it a jolly song.
No makeup, no noshing, it's Yom Kippur,
Off with the Guccis, on with the Keds
No sexy business in your beds
Hungary, have patience, just five days more
Then off your toches, and welcome Sukkot
With food and drink and goodies galore
