Hi!
I'm sorry that it's not on organ but I have just discovered an intriguing recording:

Hope this might be of interest to anyone who might have wondered what Bach was doing writing in all the keys on a well tempered clavier . . . Here it is played on an excrutiatingly difficult to play unrestored clavier with Viennese action tuned well tempered in some way . . .
Best wishes
