Great Organists in Rock


The recent thread about the greatest rock guitarists got me thinking about great rock organists. Here's my list so far...who have I forgotten?

Hammond

Keith Emerson (ELP)
Jon Lord (Deep Purple)
Gregg Allman (All Bros Band)
Lee Michaels
Ken Hensley (Uriah Heep)
Doug Ingle (late Iron Butterfly)
Jerry Corbetta (Sugarloaf)
Al Kooper (BS&T, Blues Project, etc)
Booker T.
T. Lavitz (Dixie Dregs, Jazz is Dead)
Steve Winwood (Spencer Davis Group, Traffic)

Vox Continental

Doug Ingle (early Iron Butterfly)
Ray Manzerek (Doors)
77jovian
To clarify: "Organ" usually means Hammond B3 or at least that tone regardless of what's generating it, and that's what distinguishes it. Even for here.
it's keyboards, you really can't distinguish organ, electric piano, synthesier, really, that's ridiculous, even for here
ghosthouse and i are in complete agreement...add augie meyers, felix cavaliere, georgie fame, alan price.
Dunno how "great" they are (though I do enjoy many of the previously posted musicians)...here are a few of my favorites I don't think have been listed so far:

Matthew Fisher (Procol Harum)
Brian Auger
Rod Argent
Neil Larsen on Hammond B-3 Organ.

Just a killer jazz fusion solo artist with CDs Jungle Feaver and Through Any Window. Played mainly with artist Kenny Loggins, George Benson, Lenoard Cohen, Robben Ford, Buzz Feiten, Ricky Lee Jones and George Harrison.
I think of Billy Preston as more of an electric pianist and didn't include him. Likewise, I think of Rick Wakeman as a synth master. Garth Hudson was an accidental omission.
Billy Preston. He played with Little Richard and The Beatles so that should make him a rock organist as well as his other exploits.
