My Response: "I see what you mean regarding what sounds like a slow Leslie effect (on this clip). Might be a mild phasing effect. It is the Church Organ. Mike has shared that he used this sound for pitch-bending (i.e., Have You Heard). I think that if you listen to this sound earlier in the song, it should clear it up. It's the same organ sound used on the bridge of Peak Hour from DOFP and the pitch bends on Thinking Is The Best Way To Travel from ISOTLC. I believe that the MkII Hammond sound had 3rd harmonic percussion, and there definitely is no percussive click on the Church Organ. There is an example of the MkII percussive Hammond sound on the fade out on one of the cuts on the "Rime" CD."
Anyone can certainly feel free to agree or disagree.
