Help: Tune in the manner of Johann Sebastian Bach from "Amadeus"

[pinkfloydhomer]

I have always loved the Bach-imitation in this scene:

I don't know who wrote it and I can't seem to find any sheet music for it (or even a midi-file).

All I can find is this

and this

I am not sure how accurate they are. For instance, the sheet music of the first one has parallel fifths, which I doubt that any Bach imitation would have.

Also, I took the sheet music from the first one and put it into MuseScore. I have attached the resulting pdf.

Could someone with a better ear than me please make an accurate transcription to sheet music of this miniature fugue?

Anyone?
