Prelude & Fugue in E major

Those of you who have been around on CB awhile will recall Henry Martin and his quest to write 24 Preludes and Fugue for Organ, a sort of WTC for organ, as it were. I've posted 5 of the 6, now here I give you #7, one of the WILDEST pieces I've ever heard in my life... the Prelude starts innocuously enough, but it is followed by a rollicking jig-like fugue that mus be a BEAR to play. (no, I did not play this, it is from a MIDI file!)
Listen and weep. (I am... I despair to ever play it live!)
