Interesting song, in my humble opinion I feel the drums intrude and distract from an otherwise excellent song.
I had a Hammond, not B3 I forget the model number, and a Leslie in my house for a year as I was looking after it as the owner was hiding stuff in his divorce!!! I played "Whiter shade of Pale" to death on it. I can still hear the hum

Lovely sound.
Enjoyed the song thanks for sharing
