Johnny Moore was Oscar Moore’s brother. When Oscar was with Nat Cole, Johnny played in a similar trio with Charles Brown, who played piano and sang. This was in the 1940s. When Charles decided to go on his own, Oscar left Nat, and joined Johnny as a duo. Then they got another singer/pianist.
After a couple of years, Oscar and Johnny split up. Oscar stopped traveling while Johnny rejoined Charles Brown. I remember seeing Oscar and Johnny playing together in Los Angeles — it was like meeting gods! Johnny used a big Super 400. He used to like to put in quite a few chord changes when he was playing — things like big, fat 9th chords. They were really modern changes, but they always fit what he was doing. He would slide into his chords sometimes, giving a good, bluesy feeling to a ballad. I think people will start talking a lot more about Johnny Moore in the future.
