Hi, I'm a brand new member. I joined so that I could send this message! The band with two Hammonds is Fats Hammond. The organist you're describing was probably Ken Clark. Was he playing the bass too? The other guy is Marty ???. The drummer is Benny Benson. The guitarist chair apparently rotates somewhat. I've heard both bebop-based and more wild guys play on the gig. It's an interesting mix. Ken goes for a varied pallet of sounds, rarely using the Jimmy Smith 888000000 - 3rd percussion. The other guy rarely strays from that general sound. It's a real struggle to have two Hammonds comping without stepping on each other.
