Here's another nugget of joy from "The Blues Brothers":
Ray Charles plays a music store owner from whom the band gets their instruments, and, as per usual, it seems, they're running up a tab.
What results here is that the legend sits in with the band for an impromptu romp through "Shake a Tail Feather", which references several dances of the 60's, also referenced in "Land of 1,000 Dances". Jake & Elwood (John Belushi & Dan Aykroyd) sing backup behind Ray, while a couple of kids are dancing on the Bluesmobile. Like, wild!
Today, Ray & Joliet Jake are in music heaven.
